OK here goes; I was out with friends and got realy wasted. When I got home my brother and his friends were all still there. They were very drunk as well. They left and he followed me to my room to talk. I was on my bed talking to my brother when we just kinda made out for a bit, i let him feel me up and then it went too far. We were the only ones left in the house and I let him go all the way with me. I know he did it inside of me and he told me he did the next morning. I have been off my period for about 10 days now and had clear discharge in my panties the day after. It was stupid and we are both scared of what maight happen should I take the morning after pill just to be sure?
