About a month ago I got heavily intoxicated. I slept with this guy, it was consensual. I wanted it. However I didn't want it without a condom because it was the last day of my "period week" during my birth control cycle and I was worried I might get pregnant. I thought he would pull out, but he didn't. I'm usually really good about taking the pills. Sometimes I'll miss one but it's rare. But the last few days I've felt sick on my stomach constantly, I've been eating everything, I've been very tired all the time, and since it was my "off" week I'm very worried I might be pregnant. My period comes next week so I might be PMSing too but since I'm 17 I'm very paranoid. We don't want a relationship and I can't afford a child. Is it possible I'm pregnant or am I overreacting?
