What happens during the cycle?
In each cycle, rising levels of the hormone oestrogen cause the ovary to develop and release an egg (ovulation). The womb lining also starts to thicken. In the second half of the cycle, the hormone progesterone helps the womb to prepare for implantation of a developing embryo. The egg travels down the fallopian tubes.
What happens to your body during the cycle?
Menstrual blood and tissue flow from your uterus through the small opening in your cervix and pass out of your body through your vagina. During the monthly menstrual cycle, the uterus lining builds up to prepare for pregnancy. If you do not get pregnant, estrogen and progesterone hormone levels begin falling.
How long is a menstrual cycle?
The menstrual cycle, which is counted from the first day of one period to the first day of the next, isn’t the same for every woman. Menstrual flow might occur every 21 to 35 days and last two to seven days. For the first few years after menstruation begins, long cycles are common.
What happen after periods?
When an egg is mature, it means it’s ready to be fertilized by a sperm cell. During this week after your period ends, the lining of your uterus starts getting thick and spongy again — which would either support a pregnancy, or get released through your vagina at the beginning of your next cycle (AKA your period).
What is the average length of a cycle?
A normal menstrual cycle could be as short as 22 days or as long as 36 days. When doctors talk about the length of your cycle, they include the days when you have your period. If you have a regular 28-day cycle you will start your period every four weeks. If you have a 22-day cycle you’ll have a period about every three weeks.
What is cycle theory?

What is a cycle diagram?
Cycle Diagram. A cycle diagram is used to show how a series of events interact repeatedly through a cycle. Some examples of topics that work well with cycle diagrams include the cycle of life, the flow of money in an economy and the carbon cycle in nature.
What does cycle length mean?
Menstrual cycle length is the number of days your menstrual cycle lasts. It is not the same as period length, which is the number of days your period lasts. The day your period starts is considered Cycle Day (CD) 1 — the start of a new menstrual cycle.
