Hi doctor I am a 19 year old female. I am a little worried about my symptoms. I am on the third day of my period and I feel incredibly nauseous and I have cramps and diarrhea. Early on in the day, I had a headache and lower back pain. I also think I have a little bit of health anxiety because of my irrational fear of throwing up. Furthermore, my mom made fish for dinner tonight and it smelled and tasted fine and I didn t eat that much, only a tiny piece (I don t like fish but my mom forces me to eat some for my health). Later, when my dad arrived home, my mom put another fish on the table which smelled pretty bad. Suddenly I got anxious that I have food poisoning and have been nauseous since. My mom and brother feel completely fine and they ate the same fish I did so I doubt I have food poisoning. I don t have a fever either. Am I just making myself paranoid and overanalyzing PMS symptoms?
