If you struggle with infertility and need to confirm ovulation, the Ovulation Double Check Home Progesterone Test for Fertility and Ovulation Tracking can help. According to their website:
The Ovulation Double Check® test is an FDA compliant and patent-pending in vitro diagnostic device that measures the presence of the Progesterone metabolites in urine. Progesterone is very low in the female body the first half of the menstrual cycle. When the ovary releases an egg, ovulation occurs and the ovary starts to produce Progesterone at a significantly high concentration. Therefore, Ovulation Double Check® tests should be taken after you believe ovulation has occurred to “Double Check” if ovulation has occurred.

The Confusing Part
When using these tests, you have to turn off the part of your mind that is looking for 2 lines to equal a positive result. These tests do not work the same as OPKs and HPTs. If you see two lines—even if one is the faintest second line you’ve ever seen—this means your progesterone level is registering as less approximately 10-12 (based on the images in their clinical research), and the result is negative. So just keep that in mind when you go to use these. Two lines are not good… you just need one to have a positive result.
