I had sex about a month ago (in a bath tub) with my 19 year old boyfriend (without a condom). I will be 16 in a week. :/
Lately I've been feeling sick, I've needed to go to the bathroom more, and I have frequent headaches and cramps. I'm not completely sure if I have missed my period yet because it's always different. Am I just paranoid? Or should I be concerned?
