Understanding Your Dates

LMP (Last Menstrual Period): Your pregnancy (gestational age) is officially counted from the *first day* of your last period, even though conception happens about 2 weeks later.

Conception Date: The actual day you likely conceived. This is about 14 days *after* your LMP for a 28-day cycle.

Due Date: This is 40 weeks (280 days) from your LMP, or 38 weeks (266 days) from your conception date.

IVF Dates: For IVF, the LMP is "created" based on your transfer date and embryo age to align with standard 40-week gestational tracking.
