Is Pregnancy Possible Through Intercourse Post Abortion?

I had an abortion on 1/21/15. Had sex 4 days later. With guy number 1. He went inside. Then had sex a week later with another guy (number 2) who came in my mouth once an then pulled out the next time 10 min later. Then I took plan b the next day. Three days later I had sex again with guy #1, an he went in me. Then two days later he went in me again. What are the chances of me being pregnant an with what guy?
