Please No Judgment

So, I got pregnant with my ex last August, had an abortion in late September and broke up in December (It's a long and emotional story so I would prefer not to get into it). Since then, I have started seeing someone new and we have been sexually active for a little over a month now. My periods are usually pretty regular, but after the traumatic experience with the abortion and complications that followed, I took a break from birth control and since then they have been a little less predictable. We have been using the "pull out method" which I know is not a credible form of bc. Anyways, one night we were out drinking and things got a little steamy and he ended up finishing inside of me. I immediately looked at my fertility calendar and saw that this was during my fertile week. My last period was May 30th and this happened late the night of the 12th/early hours of the 13th. I know it is too early to test, but what are the chances I am pregnant again?
