What is the Menstrual cycle

The menstrual cycle is regulated by hormones. It is a woman's monthly bleeding. Hormones are released by the pituitary gland in the brain to excite the ovaries during the reproductive phase. These hormones origin some of the woman's eggs, which are stored in the follicles of her ovaries, to set up to develop and mature. The follicles start producing estrogen - a hormone. During this moment increasing estrogen levels can be notice in a woman's blood. The increased estrogen from the womb coating becomes thicker in preparation for receiving a fertilized egg.

When a woman get sex within some days of the egg being released and sperm is present in her fallopian tube, the egg may grow to be fertilized (she becomes pregnant). But, if the egg is not fertilized her estrogen and progesterone levels will fall and the coating of the uterus (endometrium) will start breaking down - marking the start of her period.

The period consists of a small amount of blood and the endometrium. The bleeding is based on breaking of fine blood vessels within the womb as the lining detaches itself.

Every menstrual period generally remain about five days. Bleeding is more plentiful during the first two days.

Breast Tenderness, Nipple Enlargement And Increased Breast Size in Pregnancy

Changes and greater than before swelling and softness in the breast and nipples are one of the common very early signs of pregnancy. Many times, a woman may notice these changes and blame them on a particularly ill-fitting or uncomfortable bra or other article of clothing. But, the sensitive woman will notice these changes for what they are – a new life is beginning to grow inside her with the new pregnancy.


Nipples, mostly the dark area around the nipple called the areola, enlarge and darken in expectation of breastfeeding the new infant. These changes are due almost fully to hormone releases in the body, all in anticipation of sustaining the new life within. Some experts say the darkening of the areolas serves a purpose – helping the newly born child find the nipple easier for feeding. These changes to the breast and nipple areas should return to normal after birth.
