I’m starting to overthink now

I know I have came on here like twice but on my TikTok there’s been all this pregnant shit and it’s scaring me. I’m only 17 and my parents would kill me. I had sex Saturday night for the first time and I’ve been on birth control for over a year which I mentioned that I have taken it late before but this month of March I think I’ve taken it on time. However, the condom BROKE and I’m just scared for precum he didn’t finish because we saw that the condom broke and immediately stopped. I’m literally so scared

I also already started the placebo pills does that do anything
