Friday night I got food poisoning, was vomiting and had diarrhea all night. Saturday, my body was exhausted and I had light abdominal pain but I was feeling better. Sunday I thought I was back to normal but after I ate a meal I got really sick again. Besides puking and diarrhea I started bleeding when I peed. I am on the pill, take it everyday, and shouldn t have my period for another week and a half. At first the blood was light and a dark color, but today it is heavier and reder. I ve looked online and saw that this has happened to other women with food poisioning. At what point should I be alarmed and go to a doctor?
