Ovulation test paper is weak positive, period comes

Many women who are preparing for pregnancy will choose to use ovulation test strips to detect their ovulation, and then choose to have sex at the time when they are most likely to conceive. Many women want to know why the ovulation test paper is weakly positive but the menstruation comes. In fact, it is normal for the ovulation test paper to show a weak positive result before menstruation. Next, I will introduce you to some relevant knowledge about ovulation test strips!

1. Why is the ovulation test paper weak positive before menstruation

Doctors say that after ovulation, the egg stays in the uterus for about 14 days. If it is not fertilized during this period, the corpus luteum atrophies and stops secreting estrogen and progesterone. At this time, the blood vessels in the endometrium contract, the endometrium necrotizes and falls off, causing bleeding and forming menstruation. In other words, ovulation should occur about 14 days before the menstrual period, and the strongest positive ovulation should be about 7 days before the menstrual period. Therefore, using an ovulation test strip before menstruation will also test weakly positive.

Ovulation test strips predict ovulation by detecting the peak level of luteinizing hormone (LH). There is such a situation: some people's LH level is always relatively high, and there is always a weak positive LH after ovulation. Some people sometimes have abnormal fluctuations in LH when menstruation is about to come. These are all normal phenomena. If you want to determine pregnancy through a positive ovulation test, it is recommended to use an early pregnancy test or go directly to the hospital for an ultrasound examination, the result will be clearer.

2. What is an ovulation test strip?

Ovulation test strips are one of two commonly used ovulation detection tools at home. Although using ovulation test strips does not increase your chances of successful pregnancy if you want to get pregnant quickly, the best way is to have sex every three or four days, but there are still many expectant mothers who want to know their ovulation period. Ovulation test strips test your urine, and there is also an ovulation test kit that tests your saliva.

Ovulation test strips are used for in vitro qualitative detection of changes in the content of luteinizing hormone in women's urine, thereby determining the time of ovulation and the "safe period" in women's menstrual cycle, so as to achieve the purpose of choosing the best time for conception or using the "safe period" for contraception.

3. How to distinguish positive and strong positive ovulation test strips

There are some requirements for ovulation test strips. Generally, one in the morning and one in the afternoon will be enough at the beginning. However, when you find that the second line is gradually getting darker, you must test it every 3 hours. Do not throw away the test strips after testing. Write down the time and put them together for comparison. When you find that one test strip is the darkest in color and then begins to fade, the darkest one is the so-called strong positive, which is the so-called peak value.
