Help!

Hi guys, I’m super stressed and wondered if anyone could help ease my mind. I’m on the combination pill and take it regularly, generally with in half an hour to an hour and have never missed one. Earlier me and my boyfriend were having sex with a condom, but when we were done the condom was still inside of me and the ... was on my hands. I don’t think any of it really went inside of me but I’m afraid I’m pregnant. My birthday is in two days and it’s really put a damper on my excitement.

What do you guys think the chances are???
