I’ve been using the clear blue digital opk for 4 months now. They work like they are “supposed to”... low for a few days, then a day or two of high then a day of peak. So far it’s been the only method of <a href="https://play.google.com/store/apps/details?id=com.glow.android">tracking ovulation</a> I have been using, although last cycle I noticed I was very dry while BD and I guess I’m just curious if it’s possible to get a high or peak LH but not actually ovulate, which would explain my dry CM.
