Okay, I have a major issue. I'm 25 years old. My boyfriend and I broke up September 20 and he went back to his ex who was already pregnant. I had my period on the 6th last month for three days. We had sex a day or two after it ended and lately for a few days I've been feeling nauseated and a lot of certain smells make me wanna puke and I never get sick. I don't know what to do. What do I do? Someone help.
