U sound sick, that doesn't really sound like pregnancy sickness.
I've had morning sickness my whole pregnancy I'm 23 weeks I take Zofran twice a day now and it somewhat helps
Upset stomach and cramps sounds like a bug or food poisening. Morning sickness is usually nausea or vomitting alone and tends to last weeks on end unfortunately!
My morning sickness was just puking. No diarrhea! Idk if thats normal and I have had dizzy spells before they just told me to eat more protein
