New to OPK


Hey everyone,

I am just looking for some help around OPKs, when do you guys usually test? I've read that a surge happens later during the day so it's best not to test with first urine. My problem is, I drink a lot of water throughout the day and im thinking my results aren't right since my urine is diluted.

Has anyone else had this issue? Also there's so much conflicting info around how long you should not drink water for 2 hours or 4?
