How many days after becoming pregnant does the period stop?

If pregnancy occurs, periods usually stop 14 days after conception, i.e., on the date the next period was due.

Simply put:

1. A period is expected about 14 days after ovulation.
2. If pregnancy occurs during this time, that period doesn't happen — meaning periods stop about two weeks after conception.
3. That's why most women first realize they might be pregnant when they miss their period.
4. A pregnancy test usually turns positive 7–14 days after the missed period.
5. In other words, periods start stopping about 2 weeks after conception.
