Last week I had unprotected sex so had took the morning after pill a couple days later(inside the 72 hours) and then i had unprotected sex again on Sunday and he cmmed inside of me(didn't know at the time) . My period was supposed to of come this week and it still hasn't. I's never late if anything it's normally early, so I don't know whether it has anything to do with taking that pill a week ago or if I should be buying a pregnancy test to see if that's why?
