How many days after ovulation does menstruation come?

For girls, the ovulation period determines whether they are qualified to be a mother. During a girl's ovulation period, her chances of pregnancy are greatly increased. Some people are not sure whether they are pregnant or not. In fact, menstruation may occur about seven to ten days after ovulation. If you do not have your period during this period, girls should be careful because you may be pregnant and should go to the hospital for a check-up as soon as possible.

A woman's ovulation period is counted from the first day of menstruation to the 14th day.

The 5 days before and 4 days after ovulation are combined to form the ovulation period. So, if the menstruation is regular, it will come 14 or 15 days after ovulation, which means it will come about 10 days after ovulation. If it's irregular, then it's uncertain.

Knowing the ovulation period can help women who are planning to have a baby increase their chances of pregnancy.

When is ovulation? The ovulation period can be calculated according to the menstrual cycle. It is generally counted from the first day of the next menstrual period. Counting down 14 days or subtracting 14 days is the ovulation day. The 5 days before ovulation, the ovulation day, and the 4 days after ovulation, the sum of these three times is the ovulation period.

For example, the menstrual cycle is calculated as 30 days.

The first day of this menstruation is September 1st, so the next menstruation will be October 1st. Counting back 14 days from October 1st, September 17th is the ovulation day. The ovulation period is 5 days before ovulation, ovulation day, and 4 days after ovulation, which is the ten days from September 12th to September 21st.

As the follicle develops and matures, it gradually migrates to the surface of the ovary and protrudes outward. As the follicle approaches the surface of the ovary, the surface cells become thinner and eventually rupture. After most of the follicular fluid flows out, the egg is discharged, which is called "ovulation".

If the menstrual cycle is very regular, a woman's ovulation date is generally about 14 days before the next menstrual period. Generally, the 5 days before and 4 days after ovulation, together with the ovulation day, a total of 10 days are called the ovulation period. After the egg is released from the ovary, it can survive in the fallopian tube for 1 to 2 days, waiting for fertilization; the male's sperm can maintain its fertilization ability in the female's reproductive tract for 2 to 3 days, so it is easy to get pregnant through sexual intercourse a few days before and after the egg is released. Because it is easy to get pregnant through sexual intercourse during the ovulation period, the ovulation period is also called the fertile period or the dangerous period. Blood hormone levels, cervical mucus, vaginal exfoliated cell examination, and B-ultrasound can all help determine ovulation.
