For several months I have been using One step opk strips but rarely getting a positive. I have used them in the past fine though. Anyway a couple of months ago I brought the Clear blue advance digital ovulation test. They are giving me a peak fertility even when the strips are definitely not positive. Has anyone else had this? Thought it would be good to show the comparisons in case any one else is debating which to get.
It's possible I have a bad batch of the one step as I brought a pack of 50.
Photo one is low fertility on CBS's, pic 2 is high fertility and pic 3 is Peak and all the one step strips done in the same sample are next to them.
