Two weeks ago my fiancé had sex without any protection. I was on the pill but stopped taking it because I was on antibiotics(which he knew). But he said he didn't care. I was suppose to start yesterday and I did, but it was really light. Not even red, it was brown and it already stopped. I have been extremely moody. And I feel like I'm losing it. I have been bloated, high heart rate. Nauseous. I talked to a nurse at work and she said I could be prego or it could be because I stopped taking my pill. Do you think I am? I plan to take a test in the next couple of days. I just want to be sure I wait long enough. So?
