Some women get through their monthly periods easily with few or no concerns. Their periods come like clockwork, starting and stopping at nearly the same time every month, causing little more than a minor inconvenience.
However, other women experience a host of physical and/or emotional symptoms just before and during menstruation. From heavy bleeding and missed periods to unmanageable mood swings, these symptoms may disrupt a woman's life in major ways.
Your menstrual period is part of your menstrual cycle—a series of changes that occur to parts of your body (your ovaries, uterus, vagina and breasts) every 28 days, on average. Some normal menstrual cycles are a bit longer; some are shorter. The first day of your menstrual period is day one of your menstrual cycle. The average menstrual period lasts about five to seven days. A "normal" menstrual period for you may be different from what's "normal" for someone else.
Bleeding is considered heavy if it interferes with normal activities. Blood loss during a normal menstrual period is about 5 tablespoons, but if you have heavy menstrual bleeding, you may bleed as much as 10 to 25 times that amount each month. You may have to change a tampon or pad every hour, for example, instead of three or four times a day.
