I'm begging for someone to please just give me some reassurance. I had sex with my boyfriend about 5 days ago. We used a condom but it broke. We are almost sure he had pulled out before he came but obviously we can't be for sure and I know there is also pre-ejaculation fluid. I immediately went to get a Plan B pill and took the pill with food about 2 hours after the condom broke. But here's where I worry. I have PCOS and have been taking about 500 mg of metformin for about 3 months. I have had no period during this time and immediately stopped taking the pills after this event. So should I worry or do I have a shot at coming out pregnancy free? Please help
