ALTERNATIVE WAY TO CALCULATE DELIVERY DATE

In this method, the calculation is a bit difficult but all the same if you put your effort you will learn it.

Lets assume Mrs Sparkwell saw her last menstruation in month of May, precisely 22 May 2005 and it lasted for 4 days e.g 22,23,24,25(started on 22,the first day) Assume there are 30 days in a month.

The calculation will look like this:
MAY
1 2 3 4 5 6 7 8 9 10
11 12 13 14 15 16 17
18 19 20 21 "22" 23
24 25 26 27 28 29 30

1)Add 10 days to the first day of the last period (it will bring the date into another month entirely)
22 /05 /2005
+10 (adding 10 + 22= 32 which takes you to 2nd JUNE). Now we have new date 2 /06/ 2005)

2)Subtract 3 months from the month: 2 /06 /2005
-3 (after subtracting we will have 2 /03 /2005)

3)Add one year: ( after adding one year, you will have 2 /03 /2006

MRS SPARKWELL WILL BE DUE FOR DELIVERY ON 2ND MARCH 2006.

HOW TO CALCULATE DATE OF DELIVERY

Once a woman is pregnant, she imagines the period of time she will spend being pregnant and as she starts approaching ninth month, her thoughts will shift from this imagination to a more disturbing one. She starts to wonder when exactly or within what week is she going to put to bed. Here is how to be ahead of your Doctor.You can calculate your delivery date before your Doctor informs you about your delivery date.

Let's assume Mrs Williams saw her last
menstruation in month of August 2002
and it started on 5 of August (LAST MONTH
OF MENSTRUATION IS AUGUST,
FIRST DAY MENSTRUATION STARTED IS
5TH AUGUST)

AUGUST

1 2 3 4 "5" 6 7 8 9

1011 12 13 14 15

16 17 18 19 20 21

22 23 2425 26 27

28 29 30

To calculate:
1.Add '10' to the first day(5 Aug.) of the last menstrual period. (assume each month is 30 days).
2.subtract 3months from the month (Aug.) the last period occurred.
3. Add one year.
This is what it will look like:
Last menstruation was 5/08/2002
Then add and subtract +10/-3/1
It will give this new date 15/5/2003

(add 10 to 5=15, subtract 3 from 8=5, and add 1 year to 2002=2003). Mrs Williams will deliver her baby on 15th of may 2003 from the above calculations.
