    Ovulation Kit Test - As a Birth Control, How a Ovulation Kit Works?

    • 4.9   (5 Votes)

    Ovulation kit test is an efficient test to keep a check on the different phases of menstrual cycle. Ovulation Predictor Kit can be used on a regular basis if you are trying to get pregnant. The control line and test line determine the presence or absence of pregnancy in women.

    Spouses around the globe now rely more on ovulation predictor kits or OPKs to know when woman is most fertile. It is capable of detecting the production of luteinizing hormone, which takes place 36 hours before ovulation roughly.

    But there is no proof of using OPKs will enhance your chances of getting pregnant naturally. Throughout the cycle, regular sex is the only way of maximizing the chances of conception. Sometimes, it might get difficult to determine the fertile window by using calendar, basal temperature and studying the changes in cervical mucus especially when your cycles are irregular. That's the point where Ovulation Test Kits can help you. They are easy, quick and accurate way of predicting the ovulation in advance and let you know about your fertile window. These kits are available online, chemists and supermarkets.

    How ovulation kit works?

    But these ovulation predictor kits work? The body starts generating follicle-stimulating hormone (FSH) during the beginning of menstrual cycle, which actually facilitates the formation of follicle in either of the ovary. This follicle has and nurtures the egg. Once the follicle is matured adequately, it burst and releases an egg in fallopian tube (due to the surge of Luteinizing Hormone), which is actually ovulation.

    How to use ovulation kit

    Throughout the cycle, LH is produced in small amount but in the middle of periods LH increases dramatically. This increased quantity facilitates ovulation and OPKs help in detecting the LH surge via anti-LH antibodies present in sensitive testing membrane test. Once LH is detected, fertilization is likely to occur in next two to three days following the LH surge and peak fertility in next 36 hours post LH surge. If you are trying to attain pregnancy, predicting ovulation correctly is quite helpful.

    How to use an Ovulation Predictor Kit?

    Before using any ovulation predictor kit make sure to read the instructions as their functioning may vary a bit. Generally, OPKs has a set of test strips or the sticks. Some of the ovulation test kits have five tests while others may have ten.

    Ovulation predictor kit

    1- One should start using the tests two days before they expect to ovulate. You can use ovulation calculator if you are unsure when you will ovulate.

    2- One should test according to the early and latest dates, which you are expecting to ovulate if your cycles are irregular.

    3- OPKs have two lines- 

    • One is control line, which lets you know test is used properly and is working.
    • Second line is test line and if the test line is dark or darker than that of control line than it implies the LH is surging. There you should start having baby making sex.

    If you have tested 5 days then you have almost 80% chances of predicting ovulation and if test for 10 days then the percentage increases to 95%.

    Ovulation predictor kits available in the market

    Below are the OPKs available around the world and one can also order it online:

    1- First Response Daily Digital Ovulation Test

    2- Clearblue Advanced Digital Ovulation Test

    3- Clearblue Fertility Monitor

    4- Wondfo LH Ovulation Test Strips

    5- Fertile-Focus Personal Ovulation Microscope

    Ovulation test kits are more precise if used properly than any other methods of monitoring ovulation. They are more convenient and are widely available and easy to use.

    The best time to start using the ovulation kit is around cycle day 10. You should use it twice a day.
