Ovulation test paper changes process diagram

Ovulation test strips are used to test the highest level of progesterone converted into growth hormone, and then it can be detected whether it is the ovulation period. By using the ovulation test strip to measure the ovulation period, you can understand when a woman is ovulating, which is very helpful for pregnancy. Let's understand the changes in the ovulation test strip during the entire cycle.

1. Changes in ovulation test strips during the entire cycle

Ovulation test strips predict whether it is the ovulation period by testing the highest level of progesterone converted into growth hormone (LH). It can be used to determine the progesterone (LH) in human urine, and then determine the time of ovulation and the "safe menstruation period" in the female menstrual cycle, to achieve the purpose of choosing the golden time for pregnancy or using the "safe menstruation period" contraceptive measures. It is an external physical examination and auxiliary diagnosis of the female ovulation period. Ovulation test strips are suitable for about 30% of women and are only used as an auxiliary method for detecting ovulation in clinical medicine.

Before using it, you need to understand your basic physiological cycle to ensure that the LH surge is detected at the right time. Before using it, you need to understand your basic physiological cycle to ensure that the LH surge is detected at the right time. Testing can be done at any time of the day, but the testing time should be the same every day. Try not to urinate within 4 hours before the test. Avoid drinking too much fluid before the test. You may find it more convenient to test with your morning urine. Only in this way can the measured value be accurate.

What appears on the pregnancy test paper is the change of LH hormone in the body. If the ovulation test paper is found to be negative, it means you are now in the safe menstrual period. The closer it is to ovulation, the more slowly the pregnancy test paper will change from negative to positive. When it reaches a certain maximum value, it will gradually decrease and become negative. Everyone's circumstances are different, so there are certainly some differences between them, which I think is something to worry about.

How to use ovulation test strips

Step 1: Menstrual cycle

The first day of menstruation is until the day before the next menstruation. The number of days experienced is a physiological cycle, which is generally 26 to 35 days. Prepare a menstrual cycle chart for yourself in advance. Record the first day of your menstrual period each month. The time between two times is a physiological cycle. If you record for three or four months, you can accurately calculate the menstrual cycle time.

Ovulation: It takes one or two days for a perfect egg to travel from the ovary to the fallopian tube and then to the uterus, but these 48 hours seem so short. It usually occurs about 14 days before the next menarche.

Dangerous period of pregnancy: These 48 hours are definitely a high-risk period for pregnancy, but it does not mean that everything will be fine if you have sex during these days, because male sperm is a tenacious hunter. It can survive for about 72 hours after entering the uterus and will lie in ambush in the uterus for three days to capture the newly emerged eggs at any time. Therefore, the 3 days before and 3 days after ovulation, including about 7 days within the ovulation period, are locked as the dangerous period for pregnancy, which is the easy pregnancy stage. The remaining period of life without menstruation is the safe menstrual period.

Step 2: How to lock the dangerous period of pregnancy

The key is to first find the days in the middle and late stages of your menstrual period. It’s not complicated, as long as you can get kindergarten-level arithmetic questions. If you subtract 17 from the shortest menstrual cycle and 11 from the longest menstrual cycle, you will find the answer. For example, if the menstrual cycle is 30-32 days, use 30-17=12, 32-11=21, and the dangerous period of pregnancy is 13-21 days. The recent days are circled in big red. During this period, if you use ovulation test strips to test, a positive reaction will remind you that you are about to reach the high-risk fertility period.

Step 3: How to do it

According to the reporting method, you should first conduct testing for at least 3 months to understand the regularity of your cycle before making pregnancy plans. That is, during the dangerous period of pregnancy, you should use ovulation test strips to test before having sex every day. A positive reaction will remind you that you are about to reach the high-risk fertility period. Once you have an accurate grasp of your menstrual cycle, start taking action. In the three days before ovulation and three days after ovulation, it is enough to arrange intimate exercise appropriately.
