Why doesn't glow go by OPKs??

Question

Okay so the last two cycles were 50 day cycles. I started taking geritol and doing opk this month and get a positive opk on CD 17. So obviously my cycle will be shortened. I put in that I had a positive opk but glow hasn't changed my fertile days or expected period. Why not???

Answer

Thats odd. When i entered my positive opk, it adjusted my days.

Answer

It adjusted my days too. Maybe delete the test and result, close the app, and then try again?
