Help!!😳

Kristan

I was ovulating on the 3rd this month and had sex. We usually pull out or put a condom on in the middle of it but this time he stopped and said he felt like he was cumming but didn’t climax like he just felt like something was coming out. I ignored it can kept going and he came as usual. He said he doesn’t know if it was precum or what but I took 2 birth control pills that day (I’m usually not on BC but I had an old prescription) it’s been a week since and my boobs are starting to hurt😳 what are the chances that I’m pregnant or it’s just the effects of the birth control? I already have 2 kids and we weren’t planning on having another
