"We used this product to confirm ovulation, which we measure using LH test sticks. This was an easy to use test - the main catch is to remember that you're looking for only one line to confirm progesterone, rather than the standard two lines of other positive tests!"

"I simultaneously used 4(!) different tracking methods and found that PEARL matched the closest to what I was seeing in my own physical signs. It matched what I felt I SHOULD be seeing on my charting, but wasn’t and gave me confidence in my cycle. It adds an extra step to my morning, but I feel so much more confident about my cycle when using it."
