Hello!
I’ve started using OPk’s for the first time this cycle as my BBT is quite hard to read. My lines have been getting progressively darker over the last few days and I’ve been using Fermometer to interpret them. Yesterday I got into the ‘high’ bracket and early afternoon today the test line was almost as dark as the control. I thought I must be reaching the peak so tested again later this afternoon and the line was only very faint. Now I’m confused. The first test was at 1pm and second about 5pm.
Is it likely I could have missed the peak in such a small window? If not, are there any other explanations for this happening?
