In this article, you will learn about the Average period cycle.

The women’s reproductive cycle is complex but it can also be easy to understand when you break it down into its 4 phases.  

The period itself is a part of these phases. Let’s take a look at each phase…

The average period cycle is 28 day and it goes through every 4 phases, viz. The Menstrual Phase, The Preovulatory phase, Ovulation phase and Luteal phase.

The Menstrual Phase

This is the time when you get your period; you may have heavier or lighter bleeding during your period, depending on how much blood comes out of the vagina.

The menstrual period can last from 3 to 7 days. However, the length of the period can vary from person to person. Most periods last from 3 to 5 days. During this phase, your body sheds the lining of the uterus.   

The preovulatory Phase

This phase starts as soon as your menstrual phase has ended. In this phase, you no longer have an endometrial lining; therefore your body starts to prepare a new one all over again.

Your uterus lining starts to thicken with the numbers of blood vessels. Egg cell in your ovary starts to mature inside as it gets ready to be released from your ovaries.    An egg cell is also ripening in one of the ovaries in preparation for ovulation.

Ovulation Phase

Ovulation phase usually starts between 12 to 16 days before your next period starts. Your ovaries release the mature egg cell and you ovulate.

When you ovulate, a mature egg cell is released from your ovary and it moves into the fallopian tubes, where it is preserved to be fertilized. And if the egg is not fertilized the uterine lining is shed through the menstrual flow.

Luteal phase 

After the ovulation phase, it then begins the luteal phase( also known as postovulatory phase) where your endometrial lining continues to thicken.  

When you don’t become pregnant, your uterus shed the lining, welcoming the start of your freshly menstrual phase all over again.

The average period cycle is 28 day, however, some girls may have a longer period cycle and some even shorter.

So What Happened During Your Average Period Cycle?

Days 1-5: The Menstrual phase,  The length of the menstrual phase is 1 to 5 days; this is the day when the menstrual bleeding has begun.

Days 6-14:  The preovulatory phase  starts right after the menstrual phase. The preovulatory goes on after your period until the day of you ovulate. During this phase, the egg follicle on an ovary gets ready to release an egg. (1)

The last phase of the preovulatory phase and the ovulation phase are the fertile windows, where you are most likely to get pregnant if you have sex without using any protection or birth control.

Day 14: The ovulation phase usually happens about half of average period cycle (28 day cycle). Normal at this phase, an ovum is released from your ovary and into the fallopian tube.

Days 15- 28 The luteal phase occurs just before your period starts. This is the phase where your uterus normally gets thicker and prepares for a possible pregnancy( if you have sex without any birth control).
