What is the reason for the weak positive ovulation test paper before menstruation?

For many women, if they want to have a higher accuracy rate of pregnancy, they are willing to choose ovulation test strips before menstruation. They want to understand their ovulation situation through such a test. Many women have a weak positive result after taking the ovulation test strips before menstruation, so they want to know what's going on? In order for you to have a comprehensive understanding, let's learn about it together.

Ovulation test strips predict ovulation by detecting the peak level of luteinizing hormone (LH). Normal women maintain a small amount of luteinizing hormone (LH) in their bodies. The secretion of LH increases rapidly in the middle of the menstrual cycle, forming an LH peak, and within the next 28 hours, it stimulates the release of a mature egg, i.e. ovulation. Within 24 to 48 hours before female ovulation, the luteinizing hormone (LH) in urine will reach a peak value. If you use ovulation test paper to self-test, the result will be positive. The specific test method is generally explained on the packaging of ovulation test paper (must be done strictly according to the instructions to minimize the error). Unlike early pregnancy test paper, morning urine cannot be used, and urine samples at the same time of day should be used as much as possible. Water intake should be reduced 2 hours before urine collection, because diluted urine samples will also hinder the detection of LH peak. If the menstrual cycle is relatively regular, 14 days before the menstrual period (that is, the expected ovulation time), the first three days of this time plus the last three days, for six consecutive days of measurement; if the menstruation is irregular or abnormal, it is generally tested on the third day after the menstruation is over. Although the test paper is easy to use, due to the production process, the operator itself and other reasons, the accuracy rate is only about 75%.

Weak positive

A weak positive result on the ovulation test paper means that a woman always gets a weak positive result when using the ovulation test paper during her ovulation period, and no strong positive result is seen. There is a layer of chemical on the ovulation test paper. The amount of chemical applied on each brand of test paper is certain. When the LH in the woman's urine on the ovulation day is less than the amount applied on the test paper, no strong positive result will be detected. Usually in this case it is not that there is something wrong with the woman's body, but that the test strip is not suitable for her. If you find that the test paper is always weakly positive, you can switch to other testing products. As long as you ovulate normally, you can detect the ovulation day.

If the ovulation test paper always shows a weak positive result, it may be caused by improper use of urine, so mothers should not be bothered by the trouble and check whether they have collected urine according to the following method.
