I need some help

Logan

I haven’t had an actual period in 2-3 months, i had unprotected sex last thursday, he thought he pulled out in time but wasn’t sure if he did 100% in time. Me freaking out i took an expired pregnancy test (dumb i know) and it came back as negative. The only thing i’m feeling is bloating and i’m unsure if it’s pregnancy or water retention due to it being so hot... Let me know what y’all think!
