How many cups of water do you average daily?!

Briar • Pregnant w. my first boy. Scheduled C-Section 1/4/23💙
So last week when I went to my doctor I told her I drink 5ish cups a day. She said I should drink more but didn't specify how much more. So now I've been drinking a lot maybe around 9-10 and a girl at work yelled at me because I could be drinking too much?! What is he key number 8?! 😑🙄
