Does water really affect OPK?

Brandi
Hi everyone, I'm only just past my first month TTC and have been using OPKs. I never got a clear positive despite testing daily (sometimes multiple times a day) I read 2 pm is best time to test so I'd been doing that and evening. I know I may not have O'd yet due to just coming off the pill. However I have been thinking - I drink a ton of water during the day... is anyone else like that? Did it affect your OPK results? Is it better for me to test with fmu?
