Ocd about pregnancy

For the past couple days i’ve been having really bad anxiety about the possibility of being pregnant , i haven’t even had sex or anything tho i’ve been to my boyfriends house , Its worrying me. I don’t think im late for my period though my app said i should’ve gotten it a couple days ago even tho i don’t start that early. It’s also not helping the fact that i never feel full and i’ve seen someone say that’s a symptom and it’s giving me horrible anxiety
