Period Calculator

A period calculator is a tool that assists women in tracking and forecasting their menstrual periods. By inputting data such as previous period dates and cycle duration, it estimates future periods, ovulation dates, and fertile windows. It can be used for family planning, reproductive health education, or personal tracking.

Simply answer the following three questions

  1. When did your most recent menstruation begin?
  2.  How long was your period?
  3. What is the length of your menstrual cycle?

Now, simply click the "Track" button and you're done!

The Flawsome Period Calculator will tell you when your next period is due and will also provide important information about goods that you might be interested in.

Our period calculator predicts when your next period will begin based on your menstrual history. It's crucial to remember that everyone's body and cycle are different; therefore, this estimate should only be used as a reference. Isn't it preferable to be prepared than to be caught off guard?


A usual menstrual cycle lasts up to 28 days; however, having a slightly longer or shorter cycle is totally normal. There's no need to be concerned because this variance is quite natural. However, for girls who have irregular periods, the period calculator may not be completely accurate because calculating the date of their next period might be difficult under these conditions.

Realizing when to expect your next period allows you to make more arrangements. We all want to make the most of our trips and deserve to be carefree without having to worry about our periods.

The period calculator lets you know when your next period is due so you are not caught off guard!

Each menstrual cycle is unique, yet they all have the same characteristics:

Premenstrual Syndrome (PMS) symptoms such as headaches, bloating, and irritability may occur before your menstruation begins.

Period: Day 1 marks the start of your period and the commencement of bleeding. Periods typically last 4 to 7 days, with the highest flow occurring at the start. The average cycle lasts 28 days, although it can last anywhere from 21 to 35 days. Consult your doctor if your period lasts longer than 7 days.

Peak Ovulation: This is your most fertile period. The fertile period lasts around 6 days, with ovulation usually taking place on day 14 of a 28-day cycle. Our tracker assists in identifying these days!
