IVF Due Date Calculator: Transfer & Retrieval

Calculate due date based on egg retrieval or transfer date.

Calculating IVF Pregnancy Dates

Standard pregnancy calculators assume conception happens 14 days after the last period. In IVF, we know the exact moment of fertilization, making the due date calculation much more precise.

How it Works

  1. <strong>Egg Retrieval:</strong> Add 266 days (38 weeks).
  2. <strong>Day 3 Transfer:</strong> Add 266 days, then subtract 3 days.
  3. <strong>Day 5 Transfer:</strong> Add 266 days, then subtract 5 days.

Pregnancy FAQs

Is IVF due date more accurate?

Yes. Because the date of conception is known precisely in the lab, the estimated due date is statistically more accurate than natural conception dates.
