My SO and I had sex on the 5th of March. We had a condom (which didn’t break) and I stopped him so he didn’t cum. I’m afraid of the precum that could’ve possibly entered. This was the first time I’ve had sex, too. The next day i was spotting brown a little. I was so paranoid that I took a Plan B approximately 44 hours after having sex. Fast forward to the 12th of March, I had bleeding, which was like a period for 5-6 days. Now it has been about 3 weeks since I’ve had sex and taken Plan B. I feel very nauseous and uneasy. I think that I am stressing out too much to he point where I am making myself think that I have these symptoms. Help would be appreciated. I have no other people to talk to and I seriously feel alone in this. Is there a possibility that I am pregnant?
