Dehydration and ovulation

Anyone else have issues with dehydration due to opk testing? I’ve been wanting to test a couple times a day during predicted peak days which means drinking less water for multiple chunks of the day. I feel like it’s reduced my CM by a lot.

Obviously I should just drink more water, but how do you balance staying hydrated and getting accurate opks? Also, if I drink a lot more water today, will my CM come back fast enough?
