Scared

okay so i had unprotected sex lastnight & i was really nervous bc i told him to use a condom for the simple fact , i knew i was ovulating 🤦🏾‍♀️ but we didn't & now i'm really scared that i'm going to get pregnant bc i was at a chance of 33% chance of pregnancy. i'm very cautious of things like this, but my boy says im just overreacting. like i got to much to lose lose to be pregnant & i even told him to use a condom. idk what to do any suggestions?
