m usually suppost to start my period on the 19th of each month.Well this month I started On the 10th or 11th of this month.But it wasnt a regualr period that I usually have it lasted for two days,but It wasnt realy heavy or anything.After I got off of it a few days later I started it again,but It was only for like a hour or two. Im really concered if its normal for that to happend to females,because it has never happend to me so it was worrying me if I was pregnant.So if you have any answers for me it would be wonderful.I juss wanna know what the % could be of me being pregnant.and to top all that off I have had unprotected sex a week and half before all this,and he got off inside me.thanks a whole bunch if you can help
