I would go purchase others elsewhere then.. They sound expired or faulty if your taking them right.. Your pcos would have nothing to do with it. Pee is pee.. It would atleast say negative.
Blank means invalid sorry for the typo
... Yes I'm following the directions.... And I just bought them... Even on the package it says blank invalid I've just never had one do that let alone 4 of them. I do have pcos.. Think that might be the problem? Even if they have never done this before
Check de expiring date on de dip stick
I would check the directions that doesn't sound right
Are you following the instructions right? I've never had one go blank.
U should get a blood test done
