Ovulation test paper weak positive before menstruation

Ovulation test strips are also a way that more and more women choose to test whether the body is in the ovulation state. For normal women, the period before menstruation should be a safe period, and there is no ovulation during this period. If the ovulation test paper shows a weak positive result, it means that the female body is in the ovulation state. So what is the reason for a weak positive result when taking an ovulation test before menstruation?

Women usually ovulate about 14 days before their next menstrual period, so they usually do not ovulate before their period. However, some women still find that their premenstrual test paper shows a weak positive result. What's going on?

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.
