Hey, I'm new to this app. I recently lost my virginity and had unprotected sex. I had only been on my birth control, Sprintec, for nearly 2 weeks. I've read that you didn't need protection after the first 7 days of taking your bc. I started it June 5th, a Sunday that I started my period on. So, June 16th, we did the hanky panky and he didn't pull out. I had an appt with my doc and she said that I should have used backup protection for at least 2 months. Naturally, I freaked out and bought Plan B. Not even 24 hours has passed and I'm just wondering my odds of becoming pregnant. I'm really worried, but it says that it prevents implantation, so should I be so stressed?
