I'm so sick

I woke up this morning with diarrhea so bad it's straight water. I had intense stomache pain/cramps that's kinda on and off. I've got a low grade fever, not very high. I also got very nauseous which was weird and threw up a little bit.

Well I went back to the bathroom for the 25th time today and now I'm bleeding. ?

my period isn't due for another week, and it's been almost regular. It was sorta bright red and very little. Idk what to do now. I'm suppose to go to work tmrw and idk if I'm gonna be able to. Also I had my tubes tied last year I was getting worried maybe I had a ectopic pregnancy. Or you guys think just stoamche flu? Im so sick I'm starting to get a headache. I've slept all day, I'm so tired.

I don't think it matters but I have hashimotos to.

What kinda medicine should I take?
