Hi ladies
Just wanted to share that I’ve found that the cheap Amazon OPKs can sometimes come from a dodgy batch and not give proper readings. I got them few months ago but something didn’t seem right with them, the dye looked diluted. I thought I didn’t get my LH surge surge last month so I got some branded ones by fermometer.
This morning I used both of them as I’m pretty sure I’m about to ovulate and as seen on the picture, the green cheapie gave me way lower reading than the pink one.
So if you struggle to find your peak/high days on your OPKs they simply might be faulty.
