Actually, when you should have intercourse is not the hard one to determine as pregnancy will most likely be achieved if it’s done during the ovulation period that often lasts for two days. The real hard part is to detect when that ovulation period is. And that is where ovulation predictor kits can help.

Basically, women experience a short surge right before the ovulation period. During that surge, luteinizing hormone or LH rises to higher level. The prediction kits look for LH to detect when that surge is which in turn helps you determine when you would ovulate. Usually the ovulation will follow 12-48 hours after the surge.

It is recommended that the test will be taken from 12 noon to 8 pm at the same time everyday. How many days it will have to be taken varies in every woman according to the length of the cycle. Some may need 10, 20 or even more tests so it is suggested to buy the ovulation predictor kits in bulk.

There are many kits available for purchase. Aside from drug stores, you can also buy them online in cheap prices. For example, there is the clearblue ovulation kit or blue easy kit as known to others. To determine which brand is the best, try to visit discussion forums and newsgroup. The opinions of others will help you determine which one will work best for you.

With prediction kits, it is now easy for you to determine your ovulation period at home. Through their help, you can get your timing right for a bigger chance of pregnancy to happen. And that means easier time for you and your partner to conceive the baby that you’ve been trying hard to make.

Specifically, the kits measure the amount of LH or letuinizing hormone of women. Right before the ovulation, women’s LH level peaks. The results that the ovulation kits give showing that increase are the basis of determining when exactly a woman ovulates thus hinting the time when you will most likely conceive.

However, there are exceptions to the ability of the kits to detect the time of ovulation. The start of menopause for example can increase LH level which can cause a mistake in the reading. Also certain medical conditions like Poly Cystic Ovary Syndrome (PCOS) may result to an unreliable reading due to some hormone imbalances that may be brought by the illness.

If you have any condition that may affect the results that you can get from the tests, it would be best to check on your doctor. If everything is normal though, determine the length of your cycle to know when the testing should begin. When already on it, take the test at the same time everyday from 12 at noon up to 8 in the evening. Remember never to do it in the morning as most women have surge during that part of the day.

Basically, there are two types of ovulation test kits that you can buy. The first one is a saliva predictor. As its name implies, it uses saliva to determine the ovulation period. The second type is the ovulation test sticks. This type is the most often used and can be digital.

Examples of ovulation test sticks are first response, clearblue easy and clearplan. These tests slightly differ on how they indicate positive result. Nevertheless, they are all cheap can be purchased on drug stores, groceries and online stores.
