I am 21 and have just recently have become sexually active. I have only had sex twice. The most recent time was about 2 weeks ago and we had sex Saturday July 17. Both times my boyfriend and I didn't intend to have sex. So no protection. I took the morning after pill like 12 hours after we had intercourse. He did not ejaculate in me, he did pull out. But yesterday I began to have period cramps and got excited that I was getting my period. To my disappointment it was brown discharge and some blood spotting this morning when I pulled out the tampon. I have taken 6 tests and all of them are negative. I took one just last night and it was also negative, but I am still so scared. I have used first response and it claims it can tell you the possibility of pregnancy 6 days before the missed period. I woke this morning feeling sick. I have been so stressed with this and work. I just really need some answers please. Thank you
