Not like menstrual cramps

Ashlee
So little tmi..
I've been throwing up everything I've eaten for almost a month (I'm just about 10 weeks)
With my first, I was so sick i lost too much weight and was hospitalized. 
So this time I forced myself to eat. Throw up- eat - throw up.. I've managed to keep my weight up to only a 10lb loss. 
Lately I've also had TERRIBLE diahrea type cramps. My doctor gave me meds for the nausea Friday, and I've only thrown up 1 time since(same night). And I've now kept food down. Was so backed up (from nothing staying down) I took some prune juice last night. Cleared me right out. 
Problem- I still feel weak. And have terrible pains in my stomach.
And it sounds weird but they don't feel like baby related pains but something with my bowels. Still very worried I am wrong and there is a problem. ( saw the baby Thursday wiggling around with strong heart beat)
Has anyone ever had this type of pain ? And was it from your body getting used to food again? 
No spotting or anything. Just not sure when I should call my doctor. I feel like I've been annoying calling them every other day when I was sick 😩
