- HOW DOES IT WORK? Ovulation is the release of a mature egg from the ovary. It signals the beginning of your fertile period. A positive result indicates the presence of a high amount of LH or LH surge. The amount of LH in your body will begin to decrease after ovulation, so you’ll only get a positive result during that crucial fertile period. Once the egg is released, it is only viable for about 24 hours. After that, your fertile window is over.
- WHEN TO BEGIN TESTING? The length of the menstrual cycle is the duration from your first menstrual bleeding day to the day before the next bleeding begins. Determine the length of the menstrual cycle before the test. Please refer to the cycle chart to determine when you should start testing. If you do not know your cycle length, you may begin the test 11 days after your first period since the average cycle length is 28 days.
- HOW TO READ THE RESULTS? LH Surge: If two color bands are visible, and the test band is equal to or darker than the control band, one will probably ovulate in the next 24-48 hours. If trying to get pregnant, the best time to have intercourse is after 24 but before 48 hours. No LH Surge: Only one color band appears on the control region, or the test band appears but is lighter than the control band. This means there is no LH surge.
- PREGNANT HCG PREGNANCY TESTS measures the levels of the pregnancy hormone Human Chorionic Gonadotropin (HCG) in your urine. This hormone is produced by the cells of the embryo that will later form the placenta. The level of HCG starts to increase from its basal level of less than 5 mIU/mL directly after implantation and doubles about every 48 hours during the first weeks of pregnancy.
