What Is a Period Tracker App?

The word "period" is a term used to describe menstruation, the monthly flow of blood in women due to uterus lining shedding, which is associated with the menstrual cycle. The menstrual cycle is one of the body's mechanisms for preparing for the possibility of pregnancy. It’s a series of hormone-induced reactions that repeat their activities once a month in the female body. The reactions are triggered by the pituitary gland and the hypothalamus, which are located in the brain and connected to the female reproductive system. Menstrual cycles should happen on a regular, monthly basis and there is even a period tracker app to help people out.

The Menstrual Cycle

Typically, the menstrual cycle occurs monthly during a woman’s reproductive years, with the exception during pregnancy. The menstrual cycle consists of three major phases:

  • Follicular phase: before egg release; occurs from day 1 to 14
  • Ovulation phase: egg release (ovulation); typically occurs around day 14
  • Luteal phase: after egg release

Day one is regarded as the first day of the menstrual cycle. Menstruation happens on this day and lasts for three to eight days. By days 6 to 14, menstruation is expected to have stopped and the body gets set for the possibility of a pregnancy. Between days 14 and 25, an egg is first released from one of the ovaries and passes through the fallopian tubes to the uterus. If the egg encounters sperm during this movement, fertilization is expected to occur. The fertilized egg can then make its way to the uterus to begin development. By day 28, in the case of an unfertilized egg, the lining of the uterus sheds and the egg is destroyed, shedding along with it. After this, another round of menstrual bleeding occurs starting a new cycle.

How Do Period Tracker Apps Work?
