I'm sixteen, and after two years together I started having sex with my boyfriend. Thing have gotten rather complicated, and I haven't been able to spend time with him since January, which is when we last had sex. We always used condoms and I'm on the pill. For the last few weeks, I've been really sick to the scent of most foods in the am (I know morning sickness isn't just the morning but that's when I usually experience nausea) and my period has been totally out of whack. I didn't think much of it since its been awhile since I had sex and my doc changed my birth control pills, so I assumed it was side effects of the change. This morning a close friend told me about her aunt who still had light periods while pregnant and I'm now terrified. I don't want to be a mother yet. I know I should've thought of that before sex, but it felt right after waiting so long, and we took every safety precaution.
