I have been on Tri-Sprintec for 3 years and was put on it due to Poly cystic ovarian syndrome. Me and my boyfriend had unprotected sex about 8 or 9 days ago, he didn't ejaculate inside me, I know this because he pulled out and did it 5 or 6 minutes later on my stomach. I'm just wondering what are my odds of being pregnant? I keep stressing over this, and i'm supposed to start my period within the next week and if I keep stressing over this my period will be late and make me stress more. So, please help?
