Should I worry?

Ry

Hey Guys. I’m 5’5 and weigh 115lbs and I’m 19 years old. My bf and I had unprotected sex on the 31st of March or the 1st of April, I can’t remember exactly. As you can see I’m only on day one of my period but it hasn’t came yet. I’m usually pretty normal or sometimes off by a couple times but this time I’m a little more worried about pregnancy a little more cause of the sex. I just need positive options and advice. Please say stuff other than “take a test” I’m trying to educate myself. Thank you guys.

Edit: he pulled out early but I’m worried about Precum cause we had sex with condoms earlier that day.
