âEmptyâ literally means âcontaining nothing.â When it comes to food, empty means that that food contains little or no essential vitamins or minerals. In other words, these foods provide nothing of value to your body beyond calories that create excess pounds.
While menstruation usually begins between ages 12 and 13, it may happen at a younger or older age. The first menstrual period is called menarche.. The menstrual cycle is about four weeks long, starting on the first day of bleeding and ending when the next period begins. However, it can vary greatly when a girl first starts her period. It may skip months or come several times per month in the beginning.
The good news is that menstruation usually normalizes after about two years. Normal menstruation can last from one to eight days. For most women with regular menstrual cycles, their period will last for three to five days. That doesn't mean that anything is wrong if your period is longer or shorter. Period length can vary, and some lifestyle or medical changes may impact the duration or severity of bleeding and cramping.
