You may have heard a lot of talk about getting your period. Or may have already got it. (Congrats!) But what is going on in your body that makes you get your period? How does the menstural cycle work exactly? What is the menstrual cycle?
Put simply, the definition of menstrual cycle is the monthly process of ovulation in women. It is controlled by female hormones produced by your ovaries – mainly estrogen and progesterone. Estrogen and progesterone work together to move your body from one stage of your menstrual cycle to the next. What is the length of a menstrual cycle?
The average menstural cycle is 28 days. But anywhere between 21 to 35 days is considered normal. So don’t worry if your period doesn’t come every 28 days. This is especially true if you are new to menstruating. When you first get your period, your menstrual cycle is likely to be irregular for up to two years as your body adjusts to the new hormones running through your body.
Knowing how your menstural cycle works can help you anticipate when you’re going to get your period. Knowing what happens during your menstrual cycle can also help you understand changes you may notice in your body throughout the month. So, here goes. Menstruation
The first day of your period, or menstruation, is counted as the first day of your menstrual cycle. This is when estrogen and progesterone levels are at their lowest. This is when the lining of your uterus – a reddish fluid containing blood and tissue known as your endometrial lining – is shed and leaves your body through your vagina. This lasts anywhere from 3 to 7 days. Follicular phase
Next, your estrogen levels start to rise, prompting your period to stop. Estrogen prompts your uterine lining, or endometrium, to start to thicken. This estrogen also signals to your ovaries that it’s time to start preparing a follicle – a small liquid-filled sac on your ovaries that contains an egg that will later be released. This is why this phase is known as the follicular phase – or the pre-ovulation phase - of your menstrual cycle. Ovulation
Your estrogen levels will continue to rise until the 14th day of your menstrual cycle (if your cycle is 28 days). This is when the follicle that has been growing for the past week or so releases an egg. The egg then travels down your fallopian tubes and into your uterus. At this point, if sperm - the male reproductive cell – is present, the egg will fertilize, attach to the thickened endometrium, and a baby will grow.
The increased hormone levels during ovulation will result in increased vaginal discharge that you may notice in your knickers. Wearing a pantyliner like ALWAYS Dailies will help you feel fresh and clean during this time. Luteal phase
The next thing to happen during your menstrual cycle is a rise in progesterone and a decrease in estrogen. This is known as the luteal phase - or pre-menstrual phase. Progesterone’s job is to thicken the lining of your uterus, so that the egg you released during ovulation can successfully attach and grow inside your uterus if it was fertilized. On Days 21 to 24, progesterone reaches its peak. After this, if your egg wasn’t fertilized, progesterone levels start to drop, signalling your body to start breaking down the lining of your uterus. This is when girls and women start to experience the moodiness, hunger, and cramps of PMS – or premenstrual syndrome.
By definition, your menstrual cycle is just that – a cycle! This means that when you come to the end of it, it starts all over again. After the luteal phase, your cycle starts again on Day 1 when you get your next period.
So, now you know how your menstrual cycle works. This means you can predict when your next period is going to come and can understand changes to your body like increased vaginal discharge and period cramps.
