So my periods are pretty regular, between 26 and 29 ( this one was actually 28) and last for 4 days so nothing too concerning in terms of that.

However I did looks from day 10 to day 20 and all were negative, couple of faint lines on a couple days before predicted ovulation day but then nothing again.

Went to GP as I've been tested for pcos years ago , had bloods and they've all come back normal 🤯.

Is there another reason I could be having normal periods, normal bloods but negative opk?
