Ovulation in women is affected by the endocrine hormones of the pituitary gland and ovaries and presents cyclical changes, the length of the cycle is the same, both are 1 cycle per month, and ovulation occurs in the middle of two menstrual periods. Women's menstrual cycles can be long and short, but the interval between the day of ovulation and the start of the next menstrual period is relatively fixed, usually around 14 days. Then according to this relationship between ovulation and menstruation, the ovulation period can be estimated according to the menstrual cycle.

The estimation method is to count from the first day of the next menstrual period, and the 14 days backward or minus 14 days is the ovulation day, and the ovulation day and the first 5 days and the last 4 days together are called ovulation. This is also the rationale for the rhythm method, because the rest of the menstrual cycle is the safe period, except for the menstrual period and ovulation.

For example, if the menstrual cycle is 30 days, and the first day of this menstrual period is on September 29, then the next menstrual period will be on October 29 (September 29 plus 30 days), and then subtract 14 days from October 29, then October 15 is the day of ovulation. Ovulation is the day of ovulation and the first 5 days and 4 days after it, that is, from October 10 to 19.

Of course, the best way is to go to a regular hospital for a check-up.

Yes, what is your menstrual cycle? Do you understand the first seven and the last eight? There is an ovulation period between the 22nd and the 1st, so there is a good chance that it will happen!

Women's menstrual cycle is generally about 28 days, counting from the first day of menstruation to the first day of the next menstrual period, which is considered a complete menstrual cycle. In general, the menstrual cycle is calculated as one month, but in practice, it varies from person to person. The calculation of the menstrual cycle should include the time of menstruation, some women only calculate the time when the menstrual period is clean, so it may be considered that the menstrual cycle is shortened, the general menstrual cycle is 28 days, and it is normal to have a menstrual period at the beginning and the end of the month.

If a woman's usual menstrual cycle is regular, it will come on the 16th of the last month, and it will generally come on the 14th of the next month, with an interval of 28 days in between, so it mainly depends on the regularity of women's usual menstruation and menstrual cycle.

Menstrual life precautions:

During the menstrual period, you should try to avoid swimming, bathing, and sex, and the sanitary napkins used must be clean and soft, otherwise it may promote bacteria to enter the uterine cavity and cause inflammation, which may lead to infertility in the future. As for the use of sanitary hydrants (i.e. built-in tampons), it is best not to use them at night except for cleaning and changing them frequently. Because the water absorption of the sanitary plug is limited, and it is impossible to replace it in time after sleeping soundly at night, the menstrual blood outflow at this time is blocked, and it is likely to flow backward into the pelvis and cause endometriosis.

In addition, strenuous physical activity should be avoided during menstruation, as it is also one of the risk factors for endometriosis.

In addition, there are abnormal metabolism, hypoglycemia and hypothyroidism. Some people think that stress, study, and sleep are not good, and that autonomic dysfunction is also one of the many causes, and for some women, feeling exhausted can have other symptoms.

Ovulatory bleeding, i.e. mid-menstrual bleeding, refers to a small amount of bleeding between two normal menstrual periods, which can be accompanied by varying degrees of lower abdominal pain.

Bleeding during ovulation is a phenomenon that may occur in every female friend, under normal circumstances, the amount of bleeding is very small and cannot be observed by the naked eye, but some people will have obvious bleeding symptoms, and the severity cannot be generalized.

It is recommended that you pay attention to observation, go to a regular hospital for relevant examinations in time if there is an abnormality, make a clear diagnosis, and actively treat the symptoms under the guidance of a doctor**.

Bleeding during ovulation may occur once in a lifetime for some people, so don't worry too much.

Menstrual irregularities are characterized by abnormalities in the menstrual cycle or the amount of bleeding. Usually associated with endocrine dysfunction, ovarian, organic lesions or medications, stress, diet. It is recommended to go to the hospital for **examination and B-ultrasound examination to confirm the diagnosis and carry out targeting**.

At the same time, don't be too nervous and keep warm.
