Hello!
I have a really hard time with not drinking anything before I take an OPK and I also drink a lot of water everyday. I am wondering how important it is to hold your urine for 4 hours and not drink fluids during that time. I try to drink all my water in the morning before lunch but I have been trying to take an OPK right before leaving work around 4-5 so it is really tricky to hold it for 4 hours and not have coffee or something...
TIA for advice. This is my first month trying them.
