IVF Timeline: Week by Week, What to Expect

From your first consultation to a pregnancy test, an IVF cycle takes approximately 6-8 weeks for a fresh transfer, or 8-12 weeks if you are doing a freeze-all with a subsequent frozen embryo transfer. Here is what each phase looks like, what to expect physically and emotionally, and how to prepare.

Pre-Cycle: Weeks 1-2

Initial consultation and diagnostic workup

Your RE reviews your history, performs a transvaginal ultrasound to assess antral follicle count, and orders baseline bloodwork (AMH, FSH, estradiol, TSH, prolactin). Your partner completes a semen analysis. Results typically take 3-7 days.

Based on results, your RE designs a protocol — which medications, what doses, and whether any pre-treatment (birth control pills, estrogen priming) is needed.

Pre-Treatment: Weeks 2-4 (If Applicable)

Birth control priming

Not all protocols require this, but many clinics prescribe 2-3 weeks of birth control pills before stimulation. This suppresses your natural cycle and allows the RE to control timing and synchronize follicle growth. You may also start estrogen patches or lupron during this phase.

This phase feels uneventful — the hardest part is the waiting.

Stimulation: Days 1-10

Daily injections begin

You will inject gonadotropins (Follistim, Gonal-F, and/or Menopur) subcutaneously in your abdomen each evening, typically at a consistent time. Most patients report that the injections sting mildly but become routine within 2-3 days.

Monitoring visits

Every 1-2 days, you will have a morning ultrasound and blood draw to track follicle growth and hormone levels. Visits take 20-60 minutes. Based on results, your RE adjusts medication doses.

By day 5-6, you will likely add a GnRH antagonist (Cetrotide or Ganirelix) to prevent premature ovulation.

How you will feel

Early stimulation: mostly normal with some injection site tenderness. Mid-to-late stimulation: bloating, ovarian pressure, mood changes, fatigue. By day 8-10 with growing follicles, you may feel uncomfortably full. Avoid vigorous exercise, twisting motions, and sexual intercourse during this phase.

Trigger and Retrieval: Days 10-12

Trigger shot

When follicles reach 18-22mm, you receive a "trigger shot" (Ovidrel, HCG, or Lupron trigger) at a precise time — usually 36 hours before retrieval. This timing is non-negotiable; it initiates the final maturation of eggs within the follicles.

Egg retrieval

A 15-30 minute outpatient procedure under light sedation. A needle guided by ultrasound aspirates fluid from each follicle. You will wake up in recovery knowing how many eggs were retrieved.

Plan to rest for the remainder of the day. Cramping, spotting, and bloating are normal. Most patients return to work the next day, though some need 2 days.

Embryo Development: Days 1-6 Post-Retrieval

Day 1: Fertilization check — how many eggs fertilized normally (2PN).

Days 2-3: Embryos divide from 2-cell to 8-cell stage. Some clinics report at day 3, others wait until day 5.

Days 5-6: Surviving embryos reach blastocyst stage. This is when grading, freezing, and/or biopsy for PGT-A occurs.

Fresh Transfer or Freeze-All: Day 5-6

Fresh transfer

If your lining is adequate and there are no OHSS concerns, one embryo is transferred via a thin catheter through the cervix. The procedure takes 5-10 minutes, requires no anesthesia, and most patients describe mild pressure. Rest for 10-15 minutes afterward, then resume normal activity.

Freeze-all

If you are doing PGT-A, if progesterone rose prematurely, or if you are at OHSS risk, all blastocysts are vitrified (flash-frozen). Transfer happens in a separate FET cycle 4-8 weeks later.

The Two-Week Wait: Days 6-20

Whether fresh or frozen transfer, the wait for a pregnancy blood test (beta-hCG) is approximately 9-12 days after transfer. This is widely reported as the most anxiety-producing phase of IVF.

You will take progesterone supplementation (injections, suppositories, or both) during this time. Some clinics also prescribe estrogen support and baby aspirin.

Symptom-spotting is nearly universal but unreliable — progesterone supplementation causes symptoms identical to early pregnancy (bloating, breast tenderness, fatigue, cramping).

Beta Day and Beyond

A positive beta-hCG confirms pregnancy. A second beta 48-72 hours later should approximately double. An ultrasound at 6-7 weeks confirms a heartbeat and rules out ectopic pregnancy.

A negative beta means this cycle did not result in pregnancy. Your RE will typically schedule a follow-up consultation to discuss what happened, whether protocol adjustments are needed, and next steps.

The Bottom Line

IVF is a marathon, not a sprint. Understanding the timeline helps you plan work, travel, and emotional support in advance. The physical demands are real but manageable; the emotional demands are often the greater challenge. Build your support system before you start, not after you need it.
