My last period was September 17th and ended the 22nd. The accident happened on the 25th and we had or** he finished and then we waited 15 minutes he then put on a condom and we did it. The condom didnt break or anything we were just worried extra stuff might have been left on the base of him so i took plan b. I took it about 60 hours after it happened. I then a week later had very heavy bleeding like my period but it was two weeks early? Then around the expected time of my period I had very light spotting. I am now 3 weeks late for my period and nothing. I have taken 3 pregnancy tests and all are negative. My periods are normally very regular so i am very confused. I am not ready to have kids so please help!!!
