how much water are you drinking with your twins?

Gabby
I am currently 25 weeks +2 with twins and have an irritable uterus, so I get contractions daily, they don't hurt but are noticeable.  I try to drink 80-100oz a day but feel like I should be drinking more, as my pee is still yellow when I go.  So just curious how much water you twin mommas are drinking or what your drs have told you you should be drinking?
