Water causing nausea

Hiya ladies

I’m 6weeks pregnant at the moment I believe (exact hasn’t been confirmed yet & being Uk mommy means waiting least 12 weeks 🙄😫). However my nausea is really getting me down. This is my 2nd pregnancy, my first was a missed miscarriage at 13weeks. So I would say I’m stressed for sure.

Main problem is water! I used to drink 2L water easy daily before pregnancy now I can just about manage 200ml. Drinking it means it’ll come back up in 5mins. Milk is the same. Early mornings are the worst and I’m struggling to find anything that settles it. As a result I’m getting really dizzy and definitely peeing less

Any tips/advice?
