Ovulation Predictor Kits
3 things you should know about ovulation predictor kits
When a woman comes to see our Round Rock obgyns for preconception planning, we discuss optimizing natural fertility, which may include using ovulation predictor kits. It’s important to know when you ovulate to determine your fertile window. The fertile window is the time when a pregnancy is most likely to occur, which is usually 3-5 days before ovulation occurs. We found that in some kits, your results look a lot like a fern, the very picture of new growth and fertility!
Ovulation predictor kits measure levels of luteinizing hormone (LH)
Ovulation predictor kits work by measuring levels of luteinizing hormone (LH) in a woman’s urine. A surge in luteinizing hormone each month triggers ovulation. Once this surge occurs, ovulation normally happens within 12 to 36 hours.
You need to carefully read the instructions that come with ovulation predictor kits to determine when to begin testing. If you have a normal 28-day cycle, you will begin testing on day 11, for example. The day varies, though, depending on the length of your cycle.
Our Round Rock obgyns want to inform you of three things you may not know about ovulation predictor kits.
- Certain medications, such as progesterone, estrogen, testosterone or Clomid, may affect the results of ovulation predictor kits.
- You should reduce your liquid intake a few hours before taking the test.
- If you do not see the LH surge for two or more consecutive months of using ovulation predictor kits, you should consult our Round Rock obgyns.
Beyond ovulation kits—new ways to predict ovulation
Ovulation predictor kits continue to be popular, affordable ways to predict ovulation, but there is some new technology available for those who are looking for other options.
- The OvaCue fertility monitor uses a saliva sensor to monitor changes in the electrolyte levels in a woman’s saliva and a cervical mucus sensor to measure how mucus is being impacted by estrogen. This tells you when pregnancy is most likely to occur. Unlike traditional ovulation predictor kits, it also confirms that ovulation has already occurred.
- Personal ovulation microscopes monitor changes in a woman’s saliva to identify their fertile window. Saliva does something interesting when a woman has an estrogen surge and is ready to ovulate—it forms a pattern that looks like ferns when viewed under a microscope.
