I have irregular periods. My last period was 1st week of April then on 2nd week of June. On the last week of June, I had a protected sex with my boyfriend — with a condom, and he pulled out a minute before ejaculating, we checked the condom with water for holes and there was none. Now, I still do not have my period. I know it's normal for me since I get my period irregularly, I miss two to three periods in a row all the time. I'm just worried because I know that I had sex. What are my chances of pregnancy? I'm really, really stressed right now. Thank you.
