I had unprotected sex 4 days before my period was due. I took plan b two hours after. I have read that women have gotten their period a few days after unprotected sex but did not get their next period and were pregnant. I am expecting my period tomorrow but am worried that I’ll get this period and not the next. How long should I wait to take a pregnancy test just to be sure?
Hi Guest,
Relax. You are unlikely to get pregnant having sex within about 10 days before your period is due. At 4 days before, it's EXTREMELY unlikely you'd get pregnant.
There is no viable egg to fertilize. Your fertility is decreasing very rapidly too.
Plan B can make your next SEVERAL periods early or late. Wait at least 2 weeks before you take the pregnancy test.
Hope it helps.
