Ovulation Predictor Kits
They range in price from $20 to $50. The kits give you a negative or positive response. They are easier and more convenient to use than the BBT method and can predict ovulation 24 to 36 hours in advance in the first month of use. They are also more costly and can have false LH surges detected. A surge in LH does not necessarily mean you will ovulate even if the kit turns positive. LH surges can occur without ovulation. For example, an LH surge occurs but the follicle does not rupture to release the egg. |

This is still interpreted as a positive LH surge although there is no chance of pregnancy since no egg was released. Kits function mostly in similar manners. These tests typically are started on day 11 of a 28-day cycle and earlier if the cycles are shorter and later if the cycles are longer. For example, if your cycle is 35 days apart then start on day 14 and test for nine days. The kits are usually used for about six days on average. Many recommend using the second urine catch of the morning instead of the first one since urine can become concentrated overnight and may give false-positive results. If your cycles are irregular it can be very challenging and costly to use kits. A physician will need to get your cycles regular before kits are typically used. |
