How to Use an Ovulation Predictor Kit

by Barbie Carpenter

Take some of the guesswork out of trying to conceive by using an ovulation predictor kit every month. While some women consistently ovulate on the 14th day of their cycle, others -- those with menstrual cycles longer or shorter than the typical 28 days -- might ovulate earlier or later. Timing intercourse to your ovulation is a must in order for the sperm to meet the egg and result in a pregnancy. Find out precisely when you're ovulating with an ovulation predictor kit.

Track your menstrual cycle for a few months before using the ovulation predictor kit. Note how many days are in your cycle. This information helps you determine when to use the ovulation predictor kit.

Calculate the week you will likely ovulate by subtracting 14 days from your menstrual cycle length. For example, if you have a 30-day cycle, you will likely ovulate around cycle day 16. Your fertile window represents the week surrounding your potential ovulation day, according to the University of Maryland Medical Center.

Use the ovulation predictor kit for the week surrounding your predicted ovulation date. Place the test in your urine stream or urinate into a sterile container and submerge the test strip into the urine according to manufacturer instructions. Take the test twice a day -- once during midday -- until you receive a positive result.

Evaluate the test strip to determine whether your luteinizing hormone is surging, which is a sign of impending ovulation. Every kit is different, but the test strip will change colors or show a certain number of lines or a plus sign if it is positive. A positive result indicates that you should ovulate within 24 to 48 hours.

Have intercourse at least once a day once you receive a positive result on your test. Your body will likely release the egg within the next two days if it has experienced a luteinizing hormone surge. Regular intercourse during this interval can increase your chances of conception.

Tips

  • Use ovulation predictor kits with other fertility-checking tools and strategies to increase your odds of conception. Observe any increase in cervical mucus during the middle of your cycle. If the discharge becomes stretchy with an egg-white consistency, ovulation might soon occur.
  • You can also chart your basal body temperature throughout the month to confirm that ovulation occurred and determine how well you timed your intercourse to achieve pregnancy.
