How it works

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 highly concentration. Therefore, Ovulation Double Check® tests should be taken after you believe ovulation has occurred to “Double Check” if ovulation has occurred.

The Ovulation Double Check® test is performed exactly like a pregnancy or ovulation predictor test. Collect urine in a cup, dip the test strip, wait 5 minutes, then read your results. Fast, simple, and more cost effective than blood draws.

Ovulation Double Check® Test use with other Ovulation Tracking Tools

We have developed a few suggested protocols to use Ovulation Double Check® Tests in combination with other fertility tracking methods. The best way to pinpoint ovulation is by combining multiple ovulation tracking tools.

Cervical Mucus

This is a fluid secreted by the cervix, the production of which is stimulated by the hormone estrogen. Throughout your menstrual cycle, the amount and quality of cervical mucus that is produced will fluctuate, and by observing these changes you can begin to predict the most fertile days in your cycle. The production of cervical mucus is at its lowest (driest) immediately following your period. As ovulation approaches, cervical mucus will increase in quantity and moistness. In the days immediately preceding ovulation, the production of cervical mucus will be at its highest and the consistency of the mucus will be similar to egg whites. After ovulation, the quantity of cervical mucus begins to decline and become thicker in consistency. We suggest the following Ovulation Double Check® testing protocol when tracking cervical mucus patterns.

Test once on the last day of menstrual bleeding or on a “dry” day.

Start testing 4-5 days after cervical mucus becomes moist, watery, or eggwhite in consistency.

Stop testing when Ovulation Double Check® tests turn positive

LH Surge Monitoring

Luteinizing hormone (or LH) is always present in your urine, but it surges ~24-48 hours prior to ovulation. This LH surge triggers ovulation, the release of an egg from one of your ovaries. Ovulation kits and fertility monitors track the concentration of this hormone in urine. If you are tracking LH levels, we suggest the following Ovulation Double Check® Testing protocol:

Test once on the last day of menstrual bleeding.

Start testing 4-5 days after LH surge is detected.

Stop testing when Ovulation Double Check® tests turn positive.
