Had protected sex but unfortunately the condom broke and we noticed when he pulled out to finish. He swears up and down he pulled out in time and that I’m fine. But I’m too paranoid. 45 minutes after that incident I went and bought Plan B and literally took it in the car after. I’m freaking myself out and making myself sick about it. Also to add according to my period app I ovulated the day after this, I know those apps aren't foolproof but it’s more I’m freaking out and I need reassurance. Help
