On October 21st I lost my virginity. We used protection & checked for rips in the condom every minute. I bled a little after. I had been having PMS symptoms the following week; sore breasts, really irritated. & emotional. But I've been REALLY stressed out & scared that I could be pregnant. I was expecting my period November 2nd, & got it yesterday on November 1st, which seems to be on time. I usually get my periods a few days early. But this time was different....it was bright red blood with mucus. (which I heard isn't so abnormal because it's fresh blood. I think I had got rid of the old blood when I broke my hymen) I had HORRIBLE cramps & almost threw up. But I had this sort of pain with my last period. I took Midol, & noticed very shortly after that my cramps had stopped. But then I started spotting pinkish brownish....then it would pick up back to red, but not a lot. I haven't had any cramps since. This is scary for me because I've heard of implantation bleeding...but could it just be a change in period from stress? Please someone help
