How much water should I drink?

Tiffany

I’m currently 7 weeks pregnant and I’ve been trying to drink 2 or 3 bottles of water a day but sometimes I get so nauseous to where I can’t drink anything or else I feel like I’ll throw up, some people I know didn’t drink much water during pregnancy and there babies are fine but I heard it can cause pre term labor so I wanna be on the safe side, helppp.
