Liliana
So I had unprotected sex on April 1st. I new my period was coming so basically I had sex before my period because my mom always told me someone can get pregnant faster. But I just had my period today April 12. So what does that mean ? I can't have babies ? Or should I have sex after my period ? Or when should I try again someone pls help
