Teenagers have likely heard the phrase, “it’s just a phase” more than once in their life. We adults can be annoying sometimes. While people may or may not have phases, periods definitely do. The part of their menstrual cycle we refer to as the “period” is the first and most visible part of a larger process of phases and changes bodies go through to prepare for a potential pregnancy. If a pregnancy does not occur, the period begins, and the cycle starts again.
The four stages of the menstrual cycle are:
Phase 1: The Follicular Phase
Phase 2: The Ovulation Phase
Phase 3: The Luteal Phase
Phase 4: The Menses Phase
The Stages of the Menstrual Cycle, Explained
1: The Follicular Phase
DAYS: 14 (average)
The follicular phase is the first part of the menstrual cycle and begins right after the last period ends. During this phase, the ovary is maturing an egg within a sac (a.k.a. follicle) in preparation for the egg to be released. Basically, this is the time the egg spends getting ready before it says bye-bye to the ovary and hits the town.
Throughout this phase, estrogen levels gradually increase and get to their highest levels right before phase 2.
2: The Ovulation Phase
DAYS: 1 - 3
It’s time for that egg to hit the road! During the ovulatory phase, the egg is released from the ovary’s sac. This is the part where Ms. Egg puts on her finest fit and heads down to club Fallopian Tube to see if there are any cute sperm worth talking to. (Have we taken this metaphor too far?)
3: The Luteal Phase
DAYS: 14 (average)
Here’s where things get interesting. Actually, scratch that, this is all pretty interesting. During the luteal phase, the sac (aka “corpus luteum”) produces a hormone called progesterone in preparation for a pregnancy. Now your teen's cycle can split off in two ways: in one scenario, there is a pregnancy, and their body begins the preparation for carrying a child. In scenario two, there is no pregnancy (a.k.a Club Fallopian Tube was kind of busted). When there is no pregnancy, the corpus luteum sac dissolves (bye corpus luteum sac!), progesterone levels fall, and their period begins.
Which brings us to…
4: The Menses Phase (Your Period)
DAYS: 2 – 7
As we’ve already discussed, that stuff we call “period blood” is actually a combination of liquefied uterine lining tissue, blood, cells, and enzymes that flow from the uterus through the cervix to the vagina and out of the body. What a ride!
According to the Mayo Clinic, a period can last anywhere from two to seven days, and how you feel during that time can vary wildly based on your teen's genes and their biology. Here are some totally normal things your teen might expect to experience while their period (from the Society of Obstetricians and Gynaecologists of Canada): breast tenderness, muscle aches, abdominal cramps, headaches, lower back pain, low energy, fatigue, bloating, joint pain, acne, diarrhea or constipation, trouble sleeping.
That list may look like a lot, but most women only experience mild versions of only some of these symptoms. If you’re dealing with any of these symptoms, readily available medications like ibuprofen and naproxen can help. Warm baths, compresses, and plenty of fluids can also help ease the symptoms.
