I am not currently taking birth control. my boyfriend and i had unprotected sex so i decided to take plan B, then for some reason, we made a bad decision and had unprotected sex again, but then i got my period. So that usually means your not pregnant correct? Well we made another really bad decision and it made the same mistake, but i ended up taking Plan B again. My period just finished a little less then a week ago, and today i started to bleed again. its kind of brownish/reddish. what does this mean?
