Constantly evolving is a new series documenting the ways in which women’s bodies change. Based on the time of the month or period of life, the series hopes to highlight the magnificence of the woman’s body.
The previous “Constantly Evolving” article focused on external physical changes girls experience when going through puberty. In conjunction to evolutions in physical appearance, the female body undergoes a massive change internally with the start of ovulation and menstruation.
When girls are born their ovaries contain thousands of eggs called ova. During puberty, the ovaries begin to release estrogen and progesterone leading the lining of the uterus to become thicker.
Simultaneously, the hormones mature an egg and release it from the ovary. The egg travels through the fallopian tube and eventually reaches the uterus. This process is known as ovulation.
This lining of the uterus builds up in preparation for a fertilized egg, which would attach itself to the lining and begin developing. If there is no fertilized egg, the uterus sheds its thick lining and bleeds. The shedding of the uterus is what we call menstruation. This process then repeats month to month.
Girls most often get their periods for the first time between 9 and 14 years of age. Menstruation is often linked to weight, so many girls will not get their period until they exceed 90 pounds. If menstruation hasn’t begun by age 16, seeing a doctor is recommended. Periods may be irregular at first. With time, they begin to fall into a pattern that is easy to track and predict.
Periods can last anywhere from three to seven days. Some pain and discomfort is common, as the uterus is expanding and contracting to shed its lining. Pain can vary in severity, with some girls experiencing extreme cramping and back pain while others only find the cramps annoying. These variances are often caused by the level of prostaglandins the body releases. If experiencing severe cramps that interfere with daily life, girls should speak to their doctors to determine the cause.
Though information about menstruation is readily available, studies show that many women felt unprepared, shocked, and confused when they got their first period. The Constantly Evolving series strives to shine a light on the beauty of the female body and all the changes it endures to create and support new life. Sex education, as well as open communication about puberty, is necessary to break down stigmas and enhance appreciation for the female body.
