Know How to Calculate Menstrual Cycle Correctly

Every woman needs to understand how to calculate the correct menstrual cycle in order to predict the first day of her period each month. This is also important for couples who are planning or delaying pregnancy because it can determine the fertile period each month.

The menstrual cycle or menstruation is a period when a woman's body releases eggs from the ovaries or ovaries, then expels them from the uterus if fertilization does not occur. Menstruation usually lasts for 4–7 days.

In general, the menstrual cycle ranges from 21-35 days. This cycle is calculated from the first day of menstruation to the first day of the next menstruation. However, each woman's menstrual cycle can be different. For example, adolescent girls usually have a menstrual cycle of about 45 days, while women aged 20–30 years are around 21–38 days.

A woman's fertile period occurs during the ovulation phase, which is when the ovaries release an egg. The fertile period can occur 12-14 days before the date of the next menstruation. To make it easier to calculate the exact date of menstruation each month, you need to understand how to calculate the menstrual cycle correctly.

How to Calculate Menstrual Cycle

Here's how to calculate your menstrual cycle using a calendar correctly:

• Record the first day of your period every month.
• Calculate the total number of days from the date of the first menstruation to the date of menstruation in the following month.
• The total number of days is your menstrual cycle period.

So, if the total number of days from the date of your first period to the date of your next period is 28 days, it means that you will have your period every 28 days after the date of your last period. For a more accurate menstrual cycle calculation, it is recommended that you calculate your menstrual cycle for at least the last 6 months.

In addition to calculating your menstrual cycle manually, you can also use the menstrual calendar app on your phone or tablet to make it easier to calculate your menstrual cycle and record the length of your period.

Tips for Smooth Menstrual Cycle

If your menstrual cycle is sometimes irregular, you don't need to panic. This can happen because women do occasionally experience changes in their menstrual cycle, either sooner or later.

There are several factors that can affect the menstrual cycle, ranging from an unhealthy diet, smoking or consuming alcoholic beverages, too much exercise, and excessive stress.

Therefore, to keep the menstrual cycle running smoothly, there are several tips that you can do, namely:

• Eat nutritious foods, such as green vegetables, pumpkin seeds, eggs, fish, and tofu.
• Exercise regularly, but not too much.
• Get enough rest or sleep.
• Manage stress well.
• Avoid smoking and alcoholic beverages.

In certain cases, irregular menstrual cycles can be caused by side effects of drugs, such as antidepressants and birth control pills. Some diseases or medical conditions can also interfere with the menstrual cycle, such as PCOS, thyroid disease, and endometriosis.

Menstrual cycle disorders that persist or last for a long time are generally caused by medical disorders. Therefore, if you experience it, you should consult a doctor so that the cause can be identified and given the appropriate treatment.

If you are still confused about how to calculate your menstrual cycle or if you have an irregular menstrual cycle that makes it difficult to predict the time of your period and fertile period, please consult a doctor.
