So the Wondfo directions say you should use room temperature urine for their OPK. How long do you think I should leave it in the cup before it's room temp?
This should make for interesting experiences in the restroom at work when I want to test in the afternoon. Good thing there are 4 stalls in there...

Re: "Room Temp" Urine for Wondfo OPK's?
I remember this post...I use the Wondfos and I usually test right away..
