Chance of being pregnant.?

My boyfriend (now ex bf) came inside me on the 3rd of October and then again on the 4th. Then on the 9th I got my period. But I'm still having cramps 2 days after it ended. And I'm just wondering if there's a chance I could be pregnant even though I had my period or if it's a definite no. Everything I've read on the Internet isn't accurate to my situation and I can't base an answer off of it.
