IVF Week Calculator
IVF (In Vitro Fertilization) pregnancies have precisely timed milestones. Tracking gestational age, due date, and key pregnancy events is easier with our calculators. Whether you know your transfer date, retrieval date, or expected due date, you can get accurate pregnancy information instantly.
1. IVF Transfer Due Date Calculator
This tool calculates your pregnancy timeline from the embryo transfer date and embryo stage. It’s ideal for:
- Fresh, frozen, or donor embryo transfers
- Day 1–7 embryos including blastocysts
- Single or multiple embryos
Key outputs:
- Fertilization/conception date
- Estimated due date
- Current gestational age
- Days remaining until due date
- Beta hCG test date
- Ultrasound milestones (6 weeks, 13 weeks, 27 weeks)
- Fetal viability (24 weeks) and full-term date (37 weeks)
Example: For a Day 5 blastocyst transfer on March 10, 2026, your estimated due date is December 15, 2026, and your first ultrasound would be April 16, 2026.
2. IVF Week Calculator
The IVF Week Calculator lets you calculate your current pregnancy week and trimester using:
- Embryo transfer date

- Expected due date
Key outputs:
- Current week and days of pregnancy
- Total days pregnant
- Conception/fertilization date
- Transfer date
- Estimated due date
- Days until due date
- Current trimester

- Viability (24 weeks) and full-term (37 weeks)
Why it’s useful:
Even if you only know your due date or conception date, you can track your pregnancy week, remaining weeks, and milestones easily.
