How do you calculate how many days is in your menstral cycle?

Answer 1

THe first day of your period is day 1. Count the number of days you are bleeding and that is the length of your period. Keep counting until you get your period again and you will know how long your cycle is.

Answer 2

Well the days between 10 and 20 after ur periods are the most fertile. But also make sure once u want to get pregnent hav sex durin these days. Most impotant hav atleast 4 days break from sex because the strength of the ejaculation wil be more only if ther is a break of 4 days, So in short dont have sex after 4 days after ur perioda and wait till 10 or 11 th day thn 4 days break.

Answer 3

The easist way is to keep track in a day planner or calandar. The first day of bleeding is day 1, count until you have your next period, then you start over at day 1 with the new period.
Keep track over a few months to be able to get your average cycle length.

(Typically you ovualte half-way through your cycle)
