Whether you are the very beginning of your trying to conceive journey or well on your way, using ovulation test kits will help you understand how your body works. Finding out exactly when your body releases an egg from your ovary, ovulation, will help you pinpoint your most fertile time of the month. Two days in your cycle, the day before ovulation and the day of ovulation are when you are most likely to become pregnant.
How do ovulation tests work?
Luteinizing hormone (LH) is always present in human urine. LH increases dramatically just before women's most fertile day of the month in a process commonly referred to as the "LH Surge" This LH increase triggers ovulation, which means an egg is released from woman's ovary.
What time of day should I use my ovulation tests?
The best times to test are between 11 am and 3 pm and 5 pm and 10 pm. If you want to make sure that you catch your LH surge, you may want to test twice a day, once in the earlier time frame and the other in the later time frame. Please keep in mind that while you may have the initial surge of LH earlier in the day if testing via blood tests, you will not get a positive result on the ovulation test until 4-5 hours later when the surge actually reaches your urine. Be sure to test at the same time each day.
How do I read my ovulation test?
Chances are you will see two lines for several days. The ovulation test is considered a positive result when the test line is as dark as or darker than the control line on the test.
How long after my LH surge should I ovulate?
Ovulation tests detect the ovulation hormone, luteinizing hormone (LH), which rises or 'surges' 24-36 hours before you ovulate.
Once I detect my LH surge, when should I have intercourse?
Have sex during the 48 hours following your LH Surge to maximize your chances of getting pregnant during this cycle.
Special Considerations: Some prescription drugs, such as menotropins may affect the test result. Certain rare medical conditions or the onset of menopause can cause elevated levels of LH. Some women do not ovulate every cycle and they will not see an increase in the level of LH hormone during these non-ovulating cycles. Women with Poly Cystic Ovary Syndrome (PCOS) may not get reliable results from ovulation tests. Please check with your doctor if you are unsure.
