I just want to know what are the chances of pregnancy if I had sex on February 28 and my boyfriend came inside of me. March 1 he came 8 times inside of me and on March 3 he came in me once. The thing is my periods are messed up after the birth control. I heard it takes up a few months until your cycle becomes regular. So I can't really predict when my period is going to come. my last menstrual period was January 24-28. February I didn't have a period but around the 28 of February I had light spotting then around March 1 and the 3rd I had light bleeding but no heavy bleeding yet like a period yet. March 5th through the 8th I had sex again and then again on March 11. What are the chances of pregnancy
