hi, I'm seventeen years old. My last period started around August 8th and went to the 14th. Now it's October and I haven't gotten another one. I really, really don't think I am pregnant because I haven't had sex since May. Even then it was protected, and I had three periods (June, July, August) after that. I keep getting really bad pains on my right side. It feels like something is twisting down there! I just have no idea what is going on. I am sooo stressed right now, could that be it? Any answers would be greatly appreciated. thanks.
