Why is the ovulation test paper always one dark and one shallow?

We are in the preparation stage, and we pay much attention to our body and diet. We also calculate women's menstrual period every month, and choose to have sex during women's ovulation period in order to understand the status of the egg. We also use ovulation test strips. So why are the ovulation test strips always one deep and one shallow?

Why is it that the ovulation test strips are always one dark and one shallow? The reason is that if the ovulation test paper shows one deep and one shallow, it is a weak positive, which means it is in the safe period. If the couple has sex without contraception during this period, it is easy to get pregnant. It is recommended to pay attention to the hygiene of the couple's sex life. If you want to get pregnant, you can use a pillow to lift your buttocks during sex. If you do not want to get pregnant, it is recommended that you take birth control pills within 72 hours of having sex.

This test reagent is used for in vitro determination of the changes in the content of progesterone converted into growth hormone in female urine, so as to determine the ovulation time and the "menstrual safety period" in the female physiological cycle, so as to achieve the purpose of selecting the golden time for pregnancy or using the "menstrual safety period" contraceptive measures. Ovulation test strips are suitable for about 30% of women and are only used as an auxiliary method for detecting ovulation in clinical medicine.

Normal women will ovulate every month. After an egg cell is fully developed in the uterus and ovaries, it is released from the uterus and ovaries and transmitted to the uterus through the fallopian tubes. The pregnancy process is produced by the fusion of a fully developed egg cell and sperm in the fallopian tubes. Male sperm can survive in the female reproductive system for about 24-72 hours, and an egg cell is only suitable for fertilization 24-36 hours after ovulation. Therefore, the 2-3 days before ovulation and 1-2 days after ovulation are the fertile period, that is, the 4-5 days before and after ovulation are the fertile period. This pregnancy test paper can reliably detect the highest level of LH, so that women can predict the best time to become pregnant or take contraceptive measures.
