The best time to monitor ovulation, the ovulation period should be calculated like this

Fertility is a complex process that requires high-quality sperm and mature eggs. Some female friends choose to monitor ovulation by B-ultrasound, usually starting from the 10th day of the menstrual cycle, that is, going to the hospital for examination on the 10th day of menstruation.

1. The best time for ultra-monitoring ovulation

B-ultrasound monitoring of ovulation usually starts from the 10th day of the menstrual cycle, that is, go to the hospital for examination on the 10th day of menstruation. On the tenth day after menstruation, go to the hospital to monitor the development of follicles. If the follicles are developing well, you can take the opportunity to have sex and conceive. A normal follicle develops to 1.8-2.5CM and is considered a dominant follicle. The chances of pregnancy are high if you have sex every other day during ovulation.

The normal size of a mature follicle is 18-25mm. If it is lower or larger than this standard, ovulation will not occur normally. Under normal circumstances, the follicle grows at a rate of 0.2CM per day. It is recommended that you use color ultrasound to clarify the growth and development of the follicle. Starting from the 5th day after menstruation, do an ultrasound examination every other day. Perform B-ultrasound examination until ovulation. This can clarify the growth and development of the follicle, as well as whether ovulation has occurred.

2. Methods for calculating ovulation period

There are many ways to calculate the ovulation period. The most commonly used method is based on the relationship between female ovulation and menstruation. This is because female ovulation is affected by the endocrine hormones of the pituitary gland and ovaries and shows cyclical changes. The length of the cycles of the two is the same, both are one cycle per month, and ovulation occurs between two menstruations. Women's menstrual cycles vary in length, but the interval between ovulation and the start of the next menstruation is relatively fixed, usually around 14 days. Based on the relationship between ovulation and menstruation, the ovulation period can be calculated according to the menstrual cycle. The calculation method is to count from the first day of the next menstrual period, and count down 14 days or subtract 14 days to get the ovulation day. The ovulation day and the 5 days before and 4 days after are called the ovulation period.

I am not sure about your menstrual cycle now. Suppose your menstrual cycle is 30 days, and the first day of menstruation is December 27, then this menstruation should be on January 26 (December 27 plus 30 days). Then subtract 14 days from January 26, and January 12 is the ovulation day. The ovulation day and the 5 days before and 4 days after it, that is, the ten days from November 7th to 16th are the ovulation period.
