HELP!!

Meg
I had unprotected sex on the day that my period started (it was the same day but before I started). Is there any possible way that I could be pregnant? I'm sort nervous because I'm not ready to be a mom. Trust me, I know some may say that I shouldn't have had sex then, and I know that I shouldn't have... Anyway, ranting due to nerves again😂 I'm just wondering and if anyone could help, that would be great.
