I am 18 and I have a new boyfriend of almost 2 months. We've had sex 3 or 4 times unprotected but I am on birth control. I take it every day at around the same time when I'm suppose to. Lastnight we had sex and I took my birth control pill 2 hours after the time I was suppose to take it and after we had sex. I don't think he ejaculated inside me...I'm pretty sure he pulled out before he did. Today, I've been having painful cramps and I've noticed I've either gained weight or I've just been bloated. I'm suppose to get my period sometime this week or next week. I'm scared because I'm not ready to have a child but I would not be able to give it up either.
