31 weeks pregnany really sick?

Br

I don’t have a dr appt until Monday but I’m confused…so Thursday morning I was up since 1 am throwing up in insane amount of pain in my abdomen and went to the hospital. I had some contractions but I think they were Braxton hicks from just being stressed from sickness. Got an IV, nausea meds, and felt good enough to lay at home. Well I thought maybe it was food poisoning, but I’m still sick today on Saturday. I had to take zofran and was up every hour in the night trying to not throw up. I thought maybe morning sickness again? But I have cramps too and sometimes diarrhea. I’ve eaten half a bagel today and can’t stomach anything else. Is anyone else going through something similar or can help me figure out what’s wrong??
