About Menstrual Cycle
Menstrual cycle. Menstruation is a woman’s monthly bleeding. When you have your period, damaged tissue from the uterus is removed. Menstrual blood flows from the uterus through a small opening of the cervix and gets out in the body through the vagina. Most menstrual periods are 3-5 days.
When menstrual periods are regular is called a cycle. Having a regular menstrual cycle is a sign that major parts of the body are functioning normally. Also, prepares your body for pregnancy each month. A cycle is counted from the first day of menstruation until the first day of the next. Average menstrual cycle is 28 days. Cycle may fall anywhere between 21 and 35 days in adults and 21 to 45 days for teens. Increased or decreased levels of hormones during the month control the menstrual cycle.
In the first half of each menstrual cycle, estrogen levels (female hormone) starts to grow. Estrogen plays an important role in maintaining health, especially helping you to have a strong skeletal system and then to keep it so as you age. Estrogen makes the inside lining of the uterus to grow and thicken. This is where the embryo will feed, if you get pregnant. During the coating increases, an egg (ovum) matures in one of the ovaries. Around the 14th day of the 28-day cycle, the egg leaves the ovary and reaches the uterus. This is called ovulation. Hormone levels rise and help prepare the inner shell of uterus for pregnancy. It is likely that the woman remains pregnant during the three days before or the day of ovulation. Remember that women with a shorter or longer cycle than average time, ovulation may be before or after 14 days.
A woman gets pregnant if the egg is fertilized by male sperm cell and attaches to the uterine wall. Otherwise, hormone levels decreases and interior lining of the uterus is removed along with the unfertilized egg. It is possible that menstrual periods to be different every month. Period may be mild, moderate or severe, depending on the amount of blood removed. This is called menstrual flow. Period also varies. Most are between 3 and 5 days. But anyway between 2 and 7 days is normal. For the first years after the start of menstruation, the duration is common. A woman’s cycle tends to shorten and become more regular as they age.
Women may have some problems with the cycle, including pain, big bleeding or breaks.
