FAQs for Period calculator

What is a Period calculator?
A Period calculator is a tool or app that predicts the approximate dates of a person's menstrual cycles, helping individuals track and plan for their periods, ovulation, and fertility based on historical data and cycle length.
How do I calculate my period?
The average menstrual cycle is 28 days, which means the average time between periods for most girls is 28 days. So, if you want a very general estimate of when your next period is coming, count 28 days from the first day of your last period
What counts as day 1 of period?
Day 1 of your cycle is the first day of your period, meaning the first day of full flow (spotting doesn't count). During this time, the uterus sheds its lining from the previous cycle. Between days 1 – 5 of your cycle, new follicles (sacs of fluid containing eggs) begin to develop within your ovaries.
Is 22 days period cycle normal?
The length of the menstrual cycle varies from woman to woman, but the average is to have periods every 28 days. Regular cycles that are longer or shorter than this, from 23 to 35 days, are normal. The menstrual cycle is the time from the first day of a woman's period to the day before her next period.
Can I get pregnant on my period?
You may have heard you can't get pregnant on your period, but that's not entirely true. Although you're unlikely to get pregnant around or during your period, there is still a small chance you can conceive this time of the month.
