If pregnancy among women does not occur, then menstruation occurs. The menstrual cycle usually lasts about 28 days.

<h3>What do women experience during their menstrual period? </h3>

During menstruation, women may experience abdominal cramps, headaches, backache, and nausea.

The stage in which a woman is most fertile is called Ovulation. During this step, an egg is released from the follicle in the ovaries.

If a fertilized egg successfully embeds itself in the uterine lining, then the woman becomes pregnant.

If the fertilized egg does not manage to embed in the uterine lining, then menstruation will occur.

The two main hormones that control the menstrual cycle are estrogen and progesterone. If the egg is not fertilized, then progesterone levels drop.

The estrogen needs to stop FSH to be produced to make sure only one egg matures in the cycle.
