Is the second day of menstruation the follicular phase?

Many women are afraid of getting pregnant after having sex during their menstrual period. Pregnancy basically requires women to release eggs. So, will ovulation occur during menstruation? Is there a follicular phase during menstruation? Today, the editor will give you some knowledge. However, women who have sex during menstruation should be reminded that this behavior is harmful to the body and should be avoided as much as possible.

Menstrual cycle

A menstrual cycle is from the first day of menstruation to the day before the next menstruation, generally it is 28-30 days, and the normal range of menstrual cycle is 25-35 days. Normal menstrual blood is dark red, mixed with endometrial fragments and mucus, and small blood clots can be seen in a few cases. The menstrual period is generally 3-5 days, the normal range is 2-7 days, and the total amount of bleeding each time is about 50 ml.

The menstrual cycle is divided by the ovulation day into the follicular phase before ovulation and the luteal phase after ovulation. The length of the follicular phase is not fixed, but the luteal phase is about 14 days, plus or minus two days.

Phase I (Follicular Phase)

From the first day of menstruation to the day before the ovulation (LH) peak, this period is about 12-22 days, which varies from person to person due to different physical conditions. The following is an average 28-day cycle as an example:

Menstruation lasts about 3-5 days. On the 7th day, the pituitary gland will secrete hormones to stimulate the development of the egg. When the egg is mature, the pituitary gland begins to secrete estrogen to stimulate the growth of a group of 3 to 30 follicles. These follicles are supplemented in the last few days of the previous cycle to accelerate growth. When the FSH level decreases, one of the supplemented follicles is selected for ovulation, and it is dispatched immediately after maturity, while the rest enter into atrophy, and the first stage ends.

Therefore, the follicular phase only occurs after the end of menstruation, and no follicles are produced during menstruation. Therefore, the chance of pregnancy is also very low, but sexual intercourse during menstruation is not recommended. Women are more sensitive and fragile during menstruation and are likely to develop gynecological diseases due to sexual activity.
