Not holding anything down

Vanessa • 21. 1 baby, due with #2 02/07/20. Married

I’m approximately 9 weeks pregnant, I can’t hold anything at all down, not crackers, pretzels, bread, nothingggg. Tried all the little remedies, licking a lemon slice, ginger, ice pops, just about everything. My OB prescribed Reglan, which I took yesterday and all day today, and it’s been magic. But right now I just .. puked up everything. Every single thing that I ate earlier. So i need advice on what to do, how long do you ladies think this is going to last. Has anyone had this problem ?
