Hi, I'm a sufferer of HG myself, I really feel for you right now, especially being o/s!

Can you keep anything down? Can you keep fluids down? How often are you vommiting?

If you're able to keep food down (even if its only one type of food) & keep your fluids up I'd leave it for at least a few days. If it gets worse & you cant eat or drink & continue to lose weight then I'd definately head to the docs.

Something you might like to ask the doc about if you're suffering unbearably is the medication "zofran zydis", its expensive (approx $10 per tablet) but it works for me. I took it from about 6 weeks with DD & took it from 7 weeks this PG. I have to take it until I give birth but some woman are able to stop taking them throughout the pregnancy & be fine.

Just a suggestion if you get really desperate.

I hope something works soon so you can start to enjoy your pregnancy.
