One of the most common questions patients ask before starting IVF is: "How long will this take?" The honest answer is: longer than most people expect. From your initial consultation to your pregnancy blood test, a typical IVF cycle spans 6–10 weeks — and that's just one cycle. If you need diagnostic testing beforehand, or if you're doing a freeze-all followed by a frozen embryo transfer in a subsequent cycle, the total process may span 3–5 months.
This guide maps out the IVF timeline week by week — from the first consultation all the way through the two-week wait and beta hCG blood test. It also covers the separate FET (frozen embryo transfer) timeline for patients who freeze all embryos before transferring.
Overview: Two Possible Timelines
There are two main IVF timelines depending on whether you do a fresh transfer or a freeze-all with FET:
Path A: Fresh Transfer Consultation → Testing → Stimulation → Retrieval → Culture → Fresh Transfer → Two-Week Wait → Beta hCG Total: approximately 6–8 weeks from start of stimulation cycle
Path B: Freeze-All + FET Consultation → Testing → Stimulation → Retrieval → Freeze All Embryos → (optional PGT-A, 1–2 weeks) → FET Preparation → FET → Two-Week Wait → Beta hCG Total: approximately 10–14 weeks from start of stimulation to beta hCG
Most patients today fall into Path B. The reasons are explained in detail in our frozen embryo transfer guide.
Phase 1: Pre-Cycle — Weeks 1–4 (Before Stimulation Starts)
Week 1–2: Initial Consultation
Your first appointment with a reproductive endocrinologist (RE) covers your medical history, goals, and a review of any prior testing. If you've never had a fertility workup, your physician will order:
- AMH blood test (can be done any day of the cycle)
- Antral follicle count (AFC) via transvaginal ultrasound (done day 2–4 of period)
- Day 3 FSH and estradiol (timed to day 3 of menstrual cycle)
- Semen analysis (for male partners)
- Infectious disease panel (both partners)
- Uterine evaluation (sonohysterogram or hysteroscopy if indicated)
If some testing was done recently by another provider, you may be able to skip or abbreviate this phase. Some patients can start their stimulation cycle immediately; others need a full cycle of testing and protocol planning first.
At busy clinics, the wait for a consultation appointment can be 2–6 weeks. Factor this into your planning.
Week 3–4: Protocol Planning and Pre-Cycle Medications
After reviewing your test results, your RE designs your stimulation protocol. For many patients on an antagonist protocol, stimulation begins on day 2–3 of the next menstrual cycle — so you may wait 2–4 weeks for your period to arrive.
Some patients take birth control pills (BCPs) for 2–4 weeks before stimulation starts. BCPs suppress follicle development and synchronize the starting point, giving the clinic scheduling flexibility. Not all patients or protocols require this.
Phase 2: Stimulation — Days 1–14 (Typically Days 1–10 of the Stimulation Cycle)
This is the phase most people associate with IVF: the daily injections.
Day 1–2: Baseline Ultrasound
On day 2 or 3 of your stimulation cycle (counted from the first day of your period), you return for a baseline ultrasound and blood draw. This confirms:
- The ovaries are quiet — no cysts from the prior cycle
- Estradiol is appropriately suppressed
- The antral follicle count is consistent with expectations
If the baseline looks good, your nurse coordinator gives the green light to begin injections that evening.
Days 2–5: Stimulation Begins
Starting that first evening, you administer gonadotropin injections each day. The most common protocol:
- Evening injection: FSH (Gonal-F, Follistim, or Omnitrope), sometimes combined with Menopur
- Typical starting dose: 150–300 IU FSH depending on ovarian reserve and protocol
Injections take 5–10 minutes. Most patients administer them to the lower abdomen. See our detailed IVF medications and injections guide for technique and dosing information.
Days 5–8: First Monitoring Visit
After 4–5 days of stimulation, you return to the clinic for:
- Transvaginal ultrasound: The embryologist or RE measures each follicle. At this point, follicles may be 8–12mm — too small to retrieve but growing
- Estradiol blood draw: Confirms estrogen is rising appropriately
Based on these results, your dose may be adjusted up or down. You'll be given a date to return for the next monitoring visit.
Monitoring visits happen early in the morning (typically 7–9 AM) because the clinic needs to process results and call you with instructions by afternoon for that evening's injection. Plan for 1–2 hour visits including waiting time.
Days 6–8: Adding the GnRH Antagonist
When lead follicles reach approximately 12–14mm, your protocol adds a GnRH antagonist (Ganirelix or Cetrotide) — a second daily injection that prevents premature ovulation. This continues through trigger night.
Days 7–11: Additional Monitoring Visits
You'll return 2–3 more times during stimulation for follicle measurements and estradiol levels. A typical monitoring schedule:
| Stimulation Day | Purpose |
|---|---|
| Day 2–3 | Baseline scan — confirm start |
| Day 5–6 | First growth check; adjust dose |
| Day 8–9 | Mid-stimulation check |
| Day 10–11 | Pre-trigger assessment |
| Day 12–13 | Final trigger confirmation (if needed) |
By the final monitoring visit, your physician is looking for:
- At least 2–3 lead follicles ≥17–18mm
- Adequate number of medium-sized follicles (14–16mm)
- Estradiol level consistent with follicle count
When these criteria are met, the trigger shot is ordered.
Phase 3: Trigger and Retrieval — Days 12–14
Trigger Night (Day 12–13)
The trigger shot must be given at a specific time — your clinic will tell you exactly when (typically 10 PM or midnight). Set a phone alarm. The trigger is the most time-critical injection of the entire cycle.
The standard hCG trigger (Ovidrel or Pregnyl) or Lupron trigger is given as a single injection that night. Do NOT give additional gonadotropin injections after the trigger — stimulation stops here.
Egg Retrieval (Day 14 — exactly 35–36 hours after trigger)
You arrive at the clinic with a driver (you cannot drive yourself due to sedation). The procedure takes 15–30 minutes and is performed under IV sedation.
What happens afterward:
- Recovery in the clinic: 1–2 hours
- Mild cramping and spotting are normal for 1–2 days
- Most patients return to desk work the next day; avoid strenuous activity for 2–3 days
- The embryologist calls you the next morning (Day 1 of embryo development) with the fertilization report
Phase 4: Embryo Development — Days 0–6 After Retrieval
The embryology lab tracks your embryos from fertilization through blastocyst development.
Day 0 (Retrieval Day)
Eggs are identified, assessed for maturity, and fertilized via ICSI or conventional insemination.
Day 1: Fertilization Report
The embryologist calls you with a fertilization update. Not all eggs fertilize — typically 70–80% of mature eggs. This is the first point of natural attrition.
Days 2–3: Cleavage Stage
Fertilized eggs divide into 4–8 cell embryos. This stage is rarely used for transfer anymore but may be assessed for growth rate.
Day 4: Morula
Cells compact together. Not a typical assessment day.
Day 5: Blastocyst Development — The Key Report
Day 5 is the most significant report of the cycle. Your embryologist calls to tell you how many embryos have reached blastocyst stage.
Not all fertilized eggs reach Day 5 blastocyst — typically 40–60% do. This is the second major point of attrition. Embryos that arrest before blastocyst often had chromosomal abnormalities; the culture process is itself a filter.
What makes a good blastocyst:
- Inner cell mass (ICM) grade: A or B (A = tightly packed cells; B = loosely packed)
- Trophectoderm (TE) grade: A or B
- Expansion grade: 3–6 (fully expanded is best)
- A 4AA blastocyst is typically considered ideal
Day 6: Late Blastocysts
Some embryos that didn't reach blastocyst on Day 5 continue developing and can be vitrified on Day 6. Day 6 blastocysts have slightly lower implantation rates than Day 5, though good quality Day 6s are still viable.
Phase 5A: Fresh Embryo Transfer (If Doing Fresh Transfer)
If you're not doing PGT-A and your physician has determined a fresh transfer is appropriate:
Day 3 (Post-Retrieval): Cleavage Stage Transfer (Less Common)
Some clinics still do Day 3 transfers in certain circumstances. The embryo has 6–8 cells and is transferred before reaching blastocyst.
Day 5 (Post-Retrieval): Blastocyst Transfer (Standard)
The embryologist selects the highest-grade blastocyst. You arrive at the clinic with a full bladder (helps visualize the uterus on abdominal ultrasound). The embryologist loads the embryo into a catheter; the RE guides it into the uterine cavity. The procedure takes 5–10 minutes and is painless for most patients.
After transfer, you rest briefly and then go home. You continue progesterone support and avoid strenuous activity.
Exploring Options Before IVF?
The IVF timeline week by week is extensive — which is why many individuals first consider whether a simpler starting point makes sense for their situation before committing to the full process.
MakeAMom makes reusable at-home insemination kits designed for a range of situations: the CryoBaby for frozen or low-volume sperm, the Impregnator for low-motility sperm, and the BabyMaker for those with vaginal sensitivities. Kits cost a fraction of clinical treatment and ship discreetly.

Phase 5B: Freeze-All + FET Timeline
If all embryos are being frozen (freeze-all strategy), the timeline splits here.
Days 5–6 Post-Retrieval: Vitrification
All blastocysts are biopsied (if doing PGT-A) or vitrified directly.
If PGT-A: Waiting for Results (2–2 weeks)
Biopsy samples are sent to a genetics laboratory. Results typically return in 7–14 days. During this time, you take no cycle medications — you're in a "rest period."
FET Prep Cycle (3–4 weeks after retrieval)
Once your period arrives (or your physician decides timing), you begin the FET preparation cycle:
| Timeline | Event |
|---|---|
| Day 2–3 of period | Start estradiol (pills, patches, or injection) |
| Day 10–14 | Lining check ultrasound — target ≥7mm |
| Day 14–16 | Add progesterone; transfer date set |
| Day 19–21 | Blastocyst transfer (5 days after starting progesterone) |
The FET cycle is significantly simpler than the stimulation cycle — fewer injections, fewer monitoring visits, and no retrieval procedure.
Phase 6: The Two-Week Wait (TWW)
Whether after fresh transfer or FET, the two-week wait is the same: approximately 10–14 days between transfer and beta hCG blood test.
Days 1–5 Post-Transfer
Implantation, if it's going to occur, typically happens 1–5 days after transfer. During this time, the embryo (by now a blastocyst or hatching blastocyst) burrows into the uterine lining and begins producing hCG.
Progesterone side effects can mimic early pregnancy symptoms — breast tenderness, bloating, fatigue, and nausea are common and do not reliably indicate whether implantation occurred. Do not read too much into physical symptoms during the TWW.
Days 6–10 Post-Transfer
Some patients take home pregnancy tests (HPTs) during this period. If you triggered with hCG (Ovidrel), residual hCG from the trigger can cause a false positive until approximately 10 days post-trigger. Many physicians advise waiting until 9–10 days post-transfer for HPT, or to simply wait for the official blood test.
Emotional management strategies:
- Focus on what you can control — medication compliance, rest, routine
- Limit excessive symptom-checking
- Lean on your support system or a fertility-focused therapist
- The two-week wait is one of the most emotionally difficult phases of IVF — normalizing this helps
Phase 7: Beta hCG Blood Test
Beta Day (10–14 Days Post-Transfer)
The beta hCG test measures the exact level of hCG in your blood. Your clinic will give you a specific date and time to come in.
Interpreting results:
| Result | Typical Action |
|---|---|
| hCG >100 mIU/mL | Strong positive; repeat test in 48 hours to confirm doubling |
| hCG 5–100 mIU/mL | Positive; may be early or borderline; repeat in 48 hours |
| hCG <5 mIU/mL | Negative; no pregnancy detected |
| hCG rising but not doubling | May indicate ectopic pregnancy or early pregnancy loss; close monitoring |
A normally progressing pregnancy doubles hCG approximately every 48–72 hours in early weeks. Your clinic will typically check beta hCG 2–3 times before ordering a first ultrasound at 6–7 weeks.
A negative beta is devastating, and there is no way to prepare for it that removes the pain. Your care team should initiate a follow-up consultation to review the cycle and plan next steps.

Common Timeline Delays — What Can Slow Things Down
- Clinic wait time for initial consultation: 2–8 weeks at busy practices
- Abnormal baseline ultrasound (cyst): May delay stimulation start by 1 cycle
- Slow or poor stimulation response: May require protocol adjustments that extend monitoring
- Insurance pre-authorization: Can delay cycle start by 2–4 weeks
- Poor PGT-A results (no euploid embryos): May require additional retrieval cycles before any transfer
- Lining issues during FET prep: Thin or unresponsive endometrium may require a longer estrogen priming phase or cycle cancellation
Frequently Asked Questions
Q: How long does a complete IVF cycle take from start to finish? A: From the start of stimulation to the beta hCG blood test, a typical IVF cycle takes 4–6 weeks. However, the total timeline from your first consultation — including diagnostic testing and pre-cycle planning — is typically 8–14 weeks. If you are doing a freeze-all cycle with PGT-A genetic testing and a frozen embryo transfer in a subsequent cycle, add another 4–6 weeks for a total of 10–14 weeks from stimulation start to beta.
Q: How many monitoring appointments are required during stimulation? A: Expect 4–6 monitoring appointments over the 8–14 day stimulation phase, typically scheduled every 2–3 days. These happen early in the morning (7–9 AM) so results can be processed and medication instructions communicated by afternoon. Plan for 1–2 hour visits including waiting time and arrange your work schedule accordingly.
Q: Why is Day 5 the most important report during embryo development? A: Day 5 is when embryos that will succeed reach blastocyst stage — the developmentally advanced structure with a distinct inner cell mass (future baby) and trophectoderm (future placenta). Only 40–60% of fertilized eggs typically reach Day 5 blastocyst stage. Embryos that don't make it often had chromosomal abnormalities, so this natural attrition is expected and reflects normal biological selection.
Q: What can delay an IVF timeline? A: Common causes of delay include clinic wait times of 2–8 weeks for initial consultations, an abnormal baseline ultrasound (cyst) requiring a postponed start, slow stimulation response requiring protocol adjustments, insurance pre-authorization delays of 2–4 weeks, poor PGT-A results requiring additional retrieval cycles, and thin or unresponsive endometrium during FET preparation.
Q: Is a frozen embryo transfer as effective as a fresh transfer? A: In most protocols, frozen embryo transfer (FET) is equivalent to or superior to fresh transfer. Vitrification achieves post-thaw survival rates of 95% or higher for blastocysts, and the freeze-all strategy allows the body to recover from stimulation, reduces OHSS risk, and enables PGT-A testing. Most IVF cycles today use the freeze-all approach.
Key Takeaways
