A panick

So I had unprotected sex while I was ovulating. I’m young so it scares me to think I could’ve gotten pregnant. He pulled out and I’m pretty sure nothing got it. But I’ve been seeing a lot of baby stuff and a lot of abortion stuff on Instagram and I don’t believe in coincidence. I just hope I’m not. Because every time my period comes late my mom accuses me of being pregnant, idk if the stress will make my period come late 😭 Any thoughts?
