Do OPK test results change as time lapse?
I took an opk at at about 4 pm today. I got busy and didn't read it until about 20 minutes later. Are opk tests similar to hpt in the fact that after the "reading time period" you could get a false reading? This is the darkest it has been yet and I am on cd 26. Any help with this would be wonderful.

They hit full darkness about 10-15mins then start drying. If it takes a bit longer than the allotted time, its not as big of a deal as it is with hpt's becuz u wont get an evap (there's usually always some sort of line). Which ones are u using? If ur having a hard time getting a positive, make sure ur using the most sensitive ones available (20mIU), if ur using say 25, 30 or more, and u only surge to a 22, u'll never get a positive and possibly miss ur window completely.
