Wondering how to use this due date calculator?
To use the due date calculator, simply add the first day of your last menstrual period and how long your periods last. For example, if your period was expected from 2nd April 2016 to 6th April 2016, then you just select April/1/2016 and add the number of days between your periods. For example, if you have your period today, after how many days will you have your next period?
How your due date is calculated?
Your due date is calculated by adding 40 weeks or 280 days to the first day of your last menstrual cycle. But it is only an estimated date. They say only about 5% kids are actually born on their due dates.
So when are you due? Does this date match with that of your Obs/Gyn if you have visited one already?
