I just want to make it stop!

I have been puking since yesterday at 3pm. :( It's a nasty stomach virus, and it's got me all worried about the baby - worried about dehydration, worried about nutrients. I called my doctor back this morning per her instructions (it's been going on longer than 12 hours). All I can (hopefully) get & keep down right now is water, although I'm feeling nauseous again, so we'll see... Anyone who knows me knows this is like the worse for me and that I absolutely HATE throwing up. :( I'm just praying the little baby will be just fine. I couldn't get the heartbeat on my at home doppler last week, because it may've been too early. I think I'm going to go give it another shot.
