Someone here had or have dizziness and vomit being pregnant in the 30 weeks...

I have had two or three days having this symptoms at home but today was worst to the point I put my knee in the floor. I had an appoitment and was cancel because the weather is really bad. I don't want to go to the emergency too (the ground is ice) because right now I feel better and something else the baby is moving every time I have it, without and with. I want to know is somebody have something similar and if is like that what are taking?
