Hi ladies! This is our first month actually charting ovulation, and I'm doing so with the help of Glow and Pregmate OPKs. I'm getting invalid readings on them. Am I doing them incorrectly? Am I not taking them enough/at the correct times of the day? The first few days I didn't know to wait five minutes before reading the results, so I know the first few are too wet/invalid. I also skipped a few days between Cycle Days 13-18 because Glows ovulation estimate was still a few days off and I wanted to try a few and see what came of it. I was supposed to ovulate Cycle Day 18 or 19, which is today.

Any help is greatly appreciated!
