Abortion knowledge?

Hey y'all, I need to ask a question, and would really appreciate if nobody judged, because this situation has been absolute hell. I had been with my boyfriend for two years, had a ring on my finger, and everything was going perfectly. I have normal 28 day cycles, like clock-work. On April 28, I found out I was expecting. My boyfriend did not take well to it and basically beat me like crazy. It was terrible. I just didn't feel like I could give this baby the life that it deserved so I opted to have a surgical abortion. I had the procedure at 7wks, 1 day on May 16th, and I healed up nicely, and I stayed away from my ex. I got my first (normal, like clock-work with the symptoms) period back on June 14-18, and continued on. On July 3rd, I was feeling absolutely awful, and I ended up going to my ex's house, and we had unprotected (I know, I am a complete idiot) sex, where he pulled out all except one time (he insists that he did, but I can tell that he's not sure). Anyway, my period was due July 12, and that date has come and gone with no symptoms of a period. At all. Is that normal for the cycles to still be this wonky after the procedure, or could I be pregnant? If I am, there is no way in hell I would ever go through an abortion again. Ladies, it was the hardest thing I've ever done, and I beat myself up over it every single day. Think long and hard on it. Thank you for any comments!
