I am 16, and went to visit my boyfriend.  Over the past week, we had sex a lot, but we always used a condom.  One day, I took my pill about 5 hours late.  A few days after, I forgot to take the pill at all.  It's been 3 days since I returned home, and today I noticed blood on my underwear.  It wasn't like a normal period, it was a brownish color.  I've been looking at other topics, and all of them say they have discharge, but I don't.  I took the pill today, so I'm not sure if this is just spotting, or something else.  I'm worried it might be a miscarriage or pregnancy because I missed my pill twice.  I'm also on Prozac (anti-depressants) but I've been having really weird mood swings the past couple days, if that means anything.  I don't know what to do because there's a lot of different things being said online about this, and I don't know what to believe.
