| Congratulations! You are pregnant and have | | | | or after the arrived date. |

| calculation is all about. This is something not very | | | | Another way to calculate due date is to go by |
| difficult as it is all about calculating the nearest | | | | Naegle's Rule which uses the method of counting 3 |
| approximate date of your delivery. A pregnancy date | | | | months back from the first day of the LMP and then |
| calculator cannot give you the exact date of the birth | | | | adding 7 days to it. The date resulting from this |
| of your baby but only an approximation as nature | | | | calculation is the due date. |
| works in mysterious ways still inexplicable to science. | | | | Pregnancy date calculation is also done by monitoring |
| To calculate due date the time honored tradition is to | | | | Basal Body Temperature (BBT) and Luteinizing |
| go by the LMP date (Last Menstrual Period). In this | | | | hormone (LH). In this method, the ovulation date is got |

| are added to the first day of the LMP on the premises | | | | date. But, this method is also not foolproof as accurate |
| that a pregnant woman would have ovulated 14 days | | | | monitoring of the BBT and LH is difficult and hence, |
| from the first day of the LMP and conception would | | | | only an approximate date can be found out. |

| 14 days (266 +14= 280). | | | | come up with the due date. The next step for some |
