I want to cry

I am 9w5d the vomitting just never seems to stop....I was in the ER last week for fluids, potassium, and zofran. Now my doc has me on different meds after my first OB visit. But NOTHING helps. I vomitted this morning at 6am, just woke up because I was so nauseous and puked at random. Today alone I have already puked 4 times...this is crazy to me and I have no idea what to do
