I'm using OPKs as my ovulation is erratic, I'm on metformin to control hormones/PCOS and last time i was TTC it helped to regulate ovulation too.
According to my calendar my fertile window starts tomorrow but today OPK was negative with a barely visible second line. Last month I had a positive a positive on 24th but much more visible negatives by now (still negative but darker than today's).
How soon would you expect to see darkening lines?
Actual ovulation day should be 23/24 but obviously with the PCOS causing hormone imbalanced that could always change!
I hate having this, nothing makes it better and I feel like a massive failure as a human being not being able to do the very basics of hormone regulation (and have the beard to show for it)
