Chance I’m pregnant?

Jasmine

Okay so I’m on the pill and I had sex with my boyfriend a few times over the past couple of weeks. I take the pill regularly and have never missed one. He used a condom to cum in me, it didn’t break or spill so I know that one was safe. But we were at it and didnt have a condom. He said he felt a bit of cum release inside me but wasn’t a lot. Other than that he cums outside of me or I swallow. I worry a lot and I’m not due to get my withdrawal bleed for a few days and I dont want to be stressing. Anyone know what the chances are that I could get pregnant if he cums outside of me?

Any help is appreciated. Thank you x
