Hi,my name is Autumn and I am 15 years old. A week ago I had unprotected sex with my boyfriend and yes he did cum inside of me. I got my period the next day so I figured I was fine. But I was informed that because I had sex a day before my period was due there was nothing I could do to stop the cycle so it was going to happen regardless. I have also been told that I can still be pregnant regardless, and for an additional piece of information my period seemed like it was fine and then it just stopped. It did not last 5 days as usual, by day 3 it had completely stopped. I'm not sure if that's a bad sign or not? I know I'm young and shouldn't be making stupid decisions like this but I would just like to know is there a chance I could be pregnant?
