Me and my boyfriend had sexual intercourse on saturday, and sunday unprotected, and he cum'd in me a lot. I wasn't worried, because i was just on my period two weeks before this. Monday we didn't have sex, but i started to have "spotting". Well, thats what i thought it was, Tuesday we had unprotected sex again, while i was spotting, but then afterwards i was bleeding heavy. Like my period, even though today is only Thursday, i have been bleeding on and off, and i am scared. What are the chances i may be pregnant?
