Last night I spend the night at my boyfriend's house and we had sex multiple times. Today morning I woke up and I went to use the bathroom and I swiped myself and I was bleeding. I think I got my period plus I haven't got last month. And I been waiting for my period actually. I was like thank god! , my legs are so sore and I'm having cramps. But my question is I wanted to know if it normal to get your period next day after having sex? Did he help to get my period to come?
