Another OPK post sorry! The one I did last night/ this morning is classed as 'high but only at 44. It wasn't quite as dark as the control line but it was very close. The ones before were gradually getting higher until the 44 last night and since then they've been decreasing. Could it be an anovulation month where it's tried to reach peak but hasn't and therefore an egg hasn't been released? Or could it be that my peak was overnight and ive just missed it? I didn't test with fmu but now I wish I did! I've attached a close up of the highest reading and an overview of the other days. I don't usually ovulated until about CD20 so this would be unusual if I ovulated on CD15.
