I'm 18 and my boyfriend and I had unprotected sex 2 days in a row. I released inside me 4 times. I was supposed to start my period the 11th. Well, I did but it was VERY VERY light. I don't even have to wear a pad. My period is always heavy and it always has been. I don't know what to think. I can't tell if I'm experiencing early signs of pregnancy because I've been sick since the 9th. Is it possible that I'm pregnant? Should I take a test of is it too soon? Please, somebody help.
