    Know the 5 Basics of Ovulation Predictor Kits - When to use? How does OPK work?

    • 4.7   (6 Votes)

    Ovulation Predictor Kits are used to find out ovulation date on your ovulation calendar. You need to know when to use OPK and how does OPK work to make sure that you use it well. You can easily increase chances of getting pregnant with the helps of Ovulation Predictor Kits.

    Ovulation Predictor Kits are tools that help women identify when they are near their ovulation day or fertility phase. An ovulation predictor kit can pinpoint the date on your ovulation calendar when you're going to ovulate and help couples maximize their chances of conceiving naturally. (1)

    Ovulation Predictor Kits work by detecting a surge in the luteinizing hormone (LH), which tends to occur roughly 36 hours prior to ovulation or just before fertility strikes with full impact. If you have sex just as the surge occurs, then you greatly increase your odds of having sperm present in time to meet the egg and fertilize it.  (2)

    1- Should I use an OPK?:

    Of course. If you can afford the tests, and you do not have a condition such as PCOS that will give you false results, then an OPK is a wonderful tool to help guide your process. (3)

    Ovulation Day, Ovulation Predictor Kit

    2- How does an OPK work?:

    An Ovulation Predictor Kit works just like a pregnancy test (it looks like one, too!). In other words, you have to pee on it. And just like a pregnancy test, one line is the control line and the second line shows whether you are ovulating or not. There are also fancy digital tests that may show you a flashy smiley face or just the word “Ovulating.” Always be sure to read the instructions from the manufacturer carefully! (4)

    3- When do I pee on an OPK?:

    Again follow the instructions given by the manufacturer. But for many people, the best time is late morning or early afternoon. Unlike a pregnancy test, it isn't necessary to take your ovulation test in the morning. However, you should test at approximately the same time each day. Drinking excessive amounts of liquid can dilute the H in your urine, so it's best to reduce your liquid intake for two hours before testing. (5)

    4- How much does it cost?:

    An ovulation predictor kit's cost depends on the brand. Sometimes the best deals can be found online. Always check for a manufacturer's coupon! 

    a- When does it not work?: Unfortunately, there are actually quite a few reasons why an ovulation predictor kit might not work correctly

    • Ovulation predictor kits won’t work when certain fertility hormones are present in the body, such as the hormone HCG.
    • Ovulation predictor kits might not work for those over 40 years old. Some women over 40 have increased levels of LH in their systems, and that can throw off the test.
    • Ovulation predictor kits might not work for those with PCOS, since women with PCOS often have high LH levels, to begin with. (6)

    b- My test is showing a flashy smiley face: If your ovulation predictor kit tells you that you have experienced your LH surge, then it is time to get busy. Your ovulation day is near and the next two days will be your most fertile! You can track your cycle on OVO fertility.

    Ovulation Day, Ovulation Calendar

    5- My OPK test NEVER showed a flashy smiley face:

    Sure, that happens sometimes. It could be because you did not ovulate this cycle. Or it could be because you missed your surge (it happened in the afternoon and you tested in the morning.) or you ovulated early, or you ovulated late. There could be any number of reasons. (7)

    This is why is it so important to combine ovulation predictor kits with other fertile symptoms - did you have egg white cervical mucus? Did your basal body temperature spike? What is the state of your cervix? Ovulation predictor kits are fine, but they are just one of many indicators of your ovulation and ovulation day.

    Spotting after periods can be due to ovulation but in most of the cases it's because of the implantation. If the spotting is brown or pinkish in color, it can be implantation bleeding. Cramping and back aches can also be a sign of early pregnancy.
