I've read that ferning microscopes measure estrogen, while OPKs measure LH. I've never used either the scopes or sticks before, but decided to for this cycle because I had accidentally discovered I had a positive LH surge on the day AF was due last month and wanted more of an idea of what might be happening.
I do use a CBFM, which gives me peaks every month, and I chart, which seems to indiciate I am ovulating.
But the ferning microscope is not even giving me a transitional ferning pattern, and I am following directions to the letter.
I read that estrogen responsible for building up endometrial lining, necessary for implantation. I am now wondering if this (aparent absence of estrogen to trigger ferning?????) could explain my two MCs.
Does anyone know more about how these work and if I am doing something wrong?
