So I had sex with my boyfriend

So I had sex with my boyfriend today , we didn’t use any protection , & today was like 32% chances of pregnancy ... but I don’t want to get on birth control too many harmful chemicals and condoms we don’t use .. I can’t deal with my hormones like it doesn’t matter what my boyfriend does I’m always ready to have sex .. surprisingly I just had my second kid after 6years smh ... I was taking medication for my hormones but I caught an allergic reaction and had to stop taking them ... I just hope I don’t get pregnant I know that sounds silly but I had sex last month everyday of my ovulation and still had a period sooo
