I am 23weeks pregnant and couldnt keep in any solid food or liquids today i drunk rehidrat but also couldnt keep it in. should i go see a doctor?

Depends: You may be able to settle your stomach by eating ice chips & taking fluids an ounce at a time every 5-10 min. If you can make pee every 8 hrs you are hydrated enough to try re-hydrating at home. You can gradually increase the fluid/attempt if tolerated. If you haven't peed in 10-12 hrs, are light headed, or have no help at home arrange to go in now.
