Every woman has faced the horror of entering their period unprepared; nothing can be worse! The menstrual period refers to the monthly cycle of women when the egg isn’t fertilized. Bleeding results from the shedding of endometrium and lasts between three to five days.

How long the period lasts can vary from one woman to the next. Starting as early as 12 to 15 years of age, the menstrual period continues throughout a woman’s life until menopause, which falls around 52 years of age.

What is the Period Cycle Calculator?

The menstrual period calculator is a simple and easy tool that helps you track your period and understand it better. The tool enables you to predict your next period based on the previous date and how long your period usually lasts.

This tracker is very beneficial if you have events and want to enter them period-free. You can plan your events around your period days if you have an idea of when they may occur. Moreover, it’s also beneficial in finding the correct information about the ideal time to get pregnant.

How Does the Menstrual Calculator Work?

Enter your last period date, period duration, and duration of your menstrual cycle

The period tracker calculator works by taking basic information regarding your period and calculating your next predicted period date. You need to enter the basic information covered below.

Your Last Period Date

First, you need to enter the date when your last period began. Ideally, this date is the first day of your menstrual cycle.

Duration of the Periods

The duration of the period varies from one woman to the other. Some women are lucky enough to experience as little as three days, while others may last for five to seven days.

Enter the average estimate of your period duration into our period estimator to calculate your expected next period date.

Duration of the Menstrual Cycle

Lastly, our next period calculator needs your menstrual cycle duration. For most women, the period cycle lasts around 28 days which is a reasonable estimate if you’re unsure about yours.

However, if you have an idea of what your cycle duration is, enter that exact value. Some women experience shorter or longer period cycle duration; as little as 27 and as much as 30 days.

How to Calculate My Next Period Date?

By using our calculator you can calculate your next period date!

The answer is simple! You can use our simple fertile period calculator to track your period and estimate your next period. With an average estimate of your last three menstrual cycle lengths, the tool predicts the date for your next period.

For example, suppose your last menstrual cycle started on 1st December and the cycle is usually 28 days. In that case, you can expect the next period date to be around 29th December. Suppose you have seven days duration; you can expect the period to end on 4th January.

Since our period predictor works with exact calculations, your period may be a little early or a little late. Yet, as an estimate, the tool is helpful in giving you an idea of when to prepare for your next period!

Why Do I Need to Track My Menstrual Period?

Keeping track of your menstrual period is necessary to avoid being surprised or entering this difficult period completely unprepared. The period cycle calculator helps you track your period so that you can play your social events, vacation, work activities, and lifestyle around it. No one wants these period days to ruin a perfect event or occasion!

Besides, women suffering from conditions like endometriosis and PCOS need to track their periods to update their doctor regarding their menstrual cycle. With the late period calculator, they can track their period to update their doctor so they can better understand the changes in their monthly cycles and recommend treatment accordingly to maintain overall health.

One of the other reasons to track your period is to know earlier when you’re pregnant since a missed period is one of the first pregnancy signs. Moreover, with your period on track, you can get a better idea about predicting ovulation to know when is the best time to get pregnant.

Ovulation; How Many Days After My Period?

Ovulation is the period when your ovaries release the egg; this is your fertile period. Since the ovaries release the egg usually two weeks before the start of your next period, these tend to be the most fertile days, the ideal time to get pregnant.

It is most unlikely to get pregnant after your period, but it can still happen. You can use our safe days calculator to find your safe period. If you have a 28-day menstrual cycle, your ovulation period may be between the 10th to 15th day of the cycle.

Since the average days for the period are three to five days, ovulation is likely to stay effective six to eleven days after your period ends. If you want to keep track of your ovulation and menstrual cycle, you should keep track of your body temperature.

How Long Does a Period Usually Last?

Periods last up to two to seven days

There is no specific limit on how long the period lasts. There is, however, a time range between two to seven days. The cycle usually changes with age, becoming shorter and more regular as one ages.

Periods do not have a fixed duration; they tend to vary from one woman to the next based on the length and flow. While the flow may be light for some, it may be heavy or moderate for others.

Final Words

Our period calculator is a perfect tool for those who want to track their period so they don’t have to enter unprepared! When you’re aware of the expected date of your next period, you can arrange your important events and days around them so you don’t have to compromise on the fun.
