Just paranoid?

Bri
So I'm on the duo birthconrtol so I'm not suppose to ovulate. Well normally my boyfriend and I use condoms just in case you know? We are young and are not ready for kids. Anyhow, the other night we had sex, it was spur of the moment and we didn't have a condom. He didn't cum inside of my I finished him off with my mouth. Even though he didn't cum inside of me I'm worried. Is there a chance even though I'm not suppose to ovulate or am I just really paranoid?
