I had a 2week period. End of January and start of February. I also got the flu during my period. After that I have felt nausea ever since. I have missed my pill 3 days and the day I had sex. He "didnt" cum inside of me. I took my pill right after but that night I woke up at 1am and throw up twice. I dont know what to think. Am I just still neaused from the flu or what? What should I do?
