If you think you know when you ovulate during your cycle, think again. One of the main reasons healthy, fertile women fail to conceive is due to poor timing of intercourse. Ovulation predictor kits are essential when you are trying to conceive because they help to identify your most fertile days. This will greatly increase your chances of becoming pregnant.
Why do I need an ovulation kit?
Most women have been taught that the average length of a woman’s menstrual cycle is 28 days, and that ovulation occurs on day 14. However, cycles can vary greatly, especially for those of us who stop taking birth control pills in order to conceive. You might find that you have much longer or shorter cycles, and ovulation does not necessarily occur halfway through your cycle. Ovulation predictor kits can help you pinpoint when you are about to ovulate, so that you can time intercourse accordingly.

How do ovulation predictor kits work?
Just before ovulation, your body produces more luteinizing hormone (LH) in order to help the mature ovum release from its protective follicle. Ovulation predictor kits detect this LH “surge” and indicate that you are in your fertile window. When your ovulation test shows a positive result, it means ovulation is likely to occur within 24 to 36 hours. You are most fertile in the 2-3 days before ovulation as well as on the day you ovulate. Many women choose to test twice a day to be sure they do not miss their LH surge, thus increasing their chances of becoming pregnant.
You have a much better chance of becoming pregnant if you can predict when ovulation is likely to occur. However, an LH surge does not guarantee that you will ovulate, and some women experience multiple LH surges throughout the course of their cycles. The only way to tell if you actually ovulated is to track your basal body temperature and look for an increased thermal shift which indicates that ovulation has occurred.

Where can I buy ovulation predictor kits?
Ovulation predictor kits are available at most supermarkets and discount stores such as Ralphs, CVS and Wal-Mart, but they only carry the digital and midstream varieties. There are several kinds of ovulation predictor kits, but they all provide the same results. The cheapest ovulation tests are available online, and some websites even offer free shipping.
- Digital tests like the Clearblue Total Digital Ovulation Test
($18.95 for 7 tests) have a digital readout display which many women find is easier to interpret than traditional lines.
- The most common ovulation tests are the midstream versions, such as the First Response Easy-Read One-Step Ovulation Predictor Test Kit
($15.95 for 7 tests), which are held directly in the stream of urine.
- The most cost-conscious ovulation kits, which are an attractive option if you plan on testing twice a day, are the BabyHopes Ovulation Test Strips. You can choose the quantity of tests you would like, and they cost from $0.60-$1.79 per test, depending on how many you order. Plus, BabyHopes offers free shipping on every order!
- Finally, consider buying a combo pack of ovulation predictor kits and home pregnancy tests such as the Combo Pack 40 (LH) Ovulation Tests + 10 Early Detection (HCG) Pregnancy Test Strip Pack by DMI
($10.52 on Amazon) to get the most for your money.
