Dear Jennifer,
Ovulation prediction kits are widely available at most drug stores. They are easy to use, simply urinate on the test stick to activate a chemical that can detect your LH surge. Most contain between five and nine test sticks and you use them when you think you are nearing ovulation.
Ovulation prediction kits do not test for ovulation. Ovulation predictor kits measure the LH surge that precedes ovulation, but can’t confirm whether you have actually ovulated. Occasionally, an egg fails to emerge from its follicle after the LH surge has occurred, a condition known as LUFS (luteinized unruptured follicle syndrome).
Ovulation prediction kits don’t indicate whether cervical mucus is conducive to fertilization. The mucus produced by the cervix, which you experience as vaginal discharge, provides a fertile environment for sperm to get to the egg, and good quality mucus will be clear, stretchy, and lubricative (consistency of raw egg white) as you approach ovulation.
The three factors that are important for pregnancy are good sperm, good egg, and good cervical mucus. The cervical mucus is one that you can observe easily and by charting each cycle can give you much information regarding fertility. Learning to monitor cervical mucus and identify your peak of fertility is key in planning to achieve a pregnancy. Deficiencies in the cycles could point to the problem. It may be hormonal and require treatment or it can be any number of other things that the chart may show. If your cycles are normal the next step would be to have your husband tested.
For your peace of mind you can get in touch with a teacher (this site has a list) for instruction on how to observe and chart your cycles. You can find an answer for your subfertility!
