Bleeding??? Help!!!

so I take the combination borth control pill and in Friday I pretty much completely forgot to take it and I took it about 17 hours later than I was supposed to. oops. then I took my next pill at my regular time. i havent done anything where semen couldve been introduced to my vagina in about two weeks. when I did the stuff a few weeks ago, I had taken two pills no more than 9 hours late on two consecutive days. i was worried I got pregnant as a week ago I experienced pink discharge ish stuff after having sex. Also about a week ago I thought today was tomorrow and I took two pills at once, thinking I missed it the day before. after that I experienced some more pink discharge. on friday when I forgot about my pill I experienced some dark brown discharge. today, I wiped and I saw some blood. It was like my period was starting. it was weird. I've taken my pills regularly since friday (today is sunday). and I'm flipping out over this a lil bit lol. i ruled out pregnancy a while ago as I have absolutely no symptoms or anything and I was taking my pill and was only a few hours late on a few pills a few days before possibly getting semen in my vagina but could this be a sign? Am I ok??? is this normal???? help!
