How Can i know the expected date of my Delivery?

The expected date of delivery can be calculated by the addition of 9 calendar months and 7 days to the date of the first day of the last period. the formula for your better undertsanding is given below:-

Expected date of delivery = 9 months + 7 days to the date of the first day of last period.

Still Sound confusing ?  :)

take for an instance, if a lady has the first day of her last menstrual period on 1 st January , by 9 calendar months it comes to be 1 October and then add seven days, hence, 8th October becomes the expected date of delivery for a lil one in this world :)
