Example: How to Track Your Pregnancy Milestones Using the Calculator
Let’s say you’re undergoing a Frozen Embryo Transfer (FET) and your embryo is 5 days old (Blastocyst).
- Embryo Transfer Date: May 10, 2026
- Embryo Age at Transfer: 5 days
- Transfer Type: Frozen Embryo Transfer (FET)
After clicking Calculate, here’s the result:
- Conception Date: May 5, 2026
- Gestational Age Today: 2 weeks, 3 days
- Due Date: February 12, 2027
- Trimester: First Trimester
- Days Until Due Date: 270 days
- First Trimester Ends: August 5, 2026
- Second Trimester Ends: November 5, 2026
What the Results Mean
- Conception Date: This is the estimated date when the embryo was created, calculated by subtracting the embryo’s age at transfer from the transfer date.
- Gestational Age Today: This indicates how far along you are in your pregnancy based on the Last Menstrual Period (LMP), which is 14 days before conception.
- Due Date: The due date is calculated as 280 days (40 weeks) from your LMP date and helps you anticipate when you can expect your baby.
- Trimester: This shows which trimester you are currently in:
- First Trimester: 0 to 13 weeks
- Second Trimester: 14 to 26 weeks
- Third Trimester: 27 weeks until birth
- Days Until Due Date: This tells you how many days are left until your baby is due.
- Trimester End Dates: The calculator also shows when each trimester ends, giving you clear milestones to prepare for in your pregnancy journey.
