Just started menstruating? A Guide for Beginners

For most women, menstruation begins in their early teens and continues into their mid or late fifties.

A cycle begins when estrogen levels rise. This triggers the lining of the uturus to thicken, and an egg to develop within one of the ovaries. In a few days, the egg is sufficiently mature to start its journey through the fallopian tubes to the uturus. Should the egg become fertilized it will attach itself to the uterus. If not, the uterus no longer needs that thick protective cushion, so the body has developed a way to rid itself. That process is menstruation.

A normal period lasts for four or five days, but some women menstruate for anywhere from two to seven days. And surprisingly, even though it feels like a lot more, menstrual bleeding totals less than 3 tablespoons of fluid per cycle.

Though bleeding is the primary sign of menstruation, it is normal to experience other symptoms, often beginning in the days leading up to the start of your period. These symptoms can vary in intensity and include cramps, pelvic pressure, sore breasts, tummy bloating, headaches and food cravings.
