If a woman is considering an ovulation prediction test, it is advisable to avoid taking liquids in large quantities during those days. If you are following a pharmacological treatment, you should consult your doctor to determine if it could alter the results. Estrogens and progesterone, present in some birth control pills and hormone therapies, are drugs that can lower LH measurements, just like testosterone. Other types of medications, on the other hand, can increase the levels of luteinizing hormone, so they should be discontinued at least three days before the ovulation test.
During the test, the ovulation test strips change color or display a signal in contact with the urine. It is important to read the instructions to correctly interpret the result. A positive result means that ovulation will occur within 24 to 36 hours, which means that if you want to conceive, it is a good time to schedule intercourse or insemination. However, it should be noted that ovulation test strips may not work in some cases, especially if the cycle is irregular.
Tests of luteinizing hormone in urine may also offer false positives for different causes, although it is not usual. In the case that a woman is not able to find LH peaks after ovulation test, it is recommended to try it for a few months or to use a more effective option such as performing a blood test to detect levels of progesterone. If the situation persists and you cannot get pregnant, it is advisable to go to a specialist to rule out a sterility problem.
Luteinizing hormone levels in the urine can also be detected through fertility monitors, which are simple-to-use digital devices that perform the same function as the ovulation test strips. There are also fertility monitors that predict ovulation through the levels of electrolytes present in saliva or basal temperature. The advantage of these devices is that they can store the information recorded during several menstrual cycles to establish a comparison.
To calculate the timing of ovulation, the first day of the last menstrual period must be taken into account and every few days. The best time to try to conceive is the same day of ovulation and the previous days since sperm can live inside the woman’s body, and therefore fertilize the ovum between 3 and 5 days after ejaculation. It is important to keep in mind that ovulation calculators only provide approximate dates.
