How Many Weeks Pregnant Am I Today?
This is the most common question during pregnancy. The answer is: complete weeks from LMP to today, counted by medical convention.
Why does the count start before conception?
- Medical convention starts the gestational count at the LMP because the exact date of ovulation and fertilization is rarely known. During the first two gestational weeks, pregnancy has not yet occurred biologically.
- In practice, when the doctor says "you are 8 weeks", they mean 8 gestational weeks (from LMP), not 8 weeks from fertilization.

The gestational count starts at the LMP by universal medical convention, because the exact date of ovulation and fertilization is rarely known precisely. This means that in the first two gestational weeks, pregnancy has not yet occurred biologically — ovulation and fertilization typically happen in weeks 2–3.
