I am new to opk's and I read on the instructions that you shouldn't drink "excess water" before taking the test. I'm not sure what counts as excess and I tend to air on the cautious side so I haven't been drinking much of any water in the morning and afternoon. I think I am getting dehydrated, and I end up drinking tons of water after the second test. Soo, I end up having to pee all night. How much water should (or shouldn't) I be drinking? Thanks in advance!
