ok so I had sex with a guy January 1st and it’s now January 24. I am on birth control and he pulled out plus we used a condom. But I’m still scared I’m pregnant my period came in January 12 and last till January 18!but it felt different it was very light all the days accept for one day when I bled a lot which led to me leaking through my pants. My periods are usually very heavy and my cramps usually kill me. My body just feels different and idk if I should worry right now, idk who to talk to.
