For those who are using OPKs, I have a question. Most things I have read say to avoid drinking liquid and urinating for a few hours beforehand.

So my question is do you follow this? If so, how strictly?

I find it hard (especially drinking water) because during your fertile window it is also recommended to drink lots of water to have good CM quality. Plus I am very susceptible to UTIs and drinking water and peeing whenever you need to are two of the biggest things you can do to prevent.
