Overthinking

hey guys, so idk why I put this upon myself. But I had my period March 3 and it was suppose to end on the 8th but I did have period sex on March 5th and my period decided to end on March 11, wasn’t heavy or anything it was like finishing up. On March 5th he sticked it in 2 and I backed out, he did wipe and make sure everything was dry before he inserted. No condom. Which is very irresponsible for me. Just wanted to see you what are the chances of me being pregnant. He didn’t finish or anything.
