I have this problem too and have mentioned it to my OB who does not give af. I drink plenty of water also but it just doesn’t help.
Definitely talk to your OB. I was getting dizzy and light headed every time I stood up, with no other symptoms.. turns out my baby had sucked all my potassium out and my body was about a day away from shutting down.
Yeh my doctor hasn’t even call me back it freaking nerve wreaking
