Okay so May 28th, I got drunk and was messing around with one of my friends, we did oral sex and he fingered me, he attempted to do anal, don't remember if he did or not but we didn't actually have sex I'm 99% sure, I'm just afraid the cum got into my vagina somehow, but May 29th the next day, I bled a little, (I never actually got my period that month but I'm a Virgin), so thinking I was getting my period I started my new birth control pill. Didn't think anything of getting pregnant, so May 31 I got a form of Plan B because I was worried, I used it within 72 hours so it will still be effective right? I'm having pregnancy symptoms and scaring myself really bad. Today is June 3rd and I'm still freaking out. I was gassy within the last week, I've had constipation and wettish poop, my head hurts today, my stomach sorta hurts on and off, it hurts to pee lately unless I drink a lot of water first, and my back hurts, so does my boobs really bad, I need help, I can't be pregnant cause I'm only 15! I know this was a dumb desicion but it's a wake up call, help me! What's going on?? Is it my birth control side effects or plan b side effects or what?
