How do you calculate conception date from due date?
In cases where the date of conception is known precisely, such as with in vitro fertilization, the EDD is calculated by adding 266 days to the date of conception. Ultrasound uses the size of the fetus to determine the gestational age (the time elapsed since the the first day of the last menstrual period).
Can you tell exact date of conception?
Knowing the exact day of conception is a difficult thing. Sperm can live in a woman’s body for up to five days, making it impossible to calculate exactly when conception occurred. It is not a fine science. In addition, women ovulate anywhere from 11 to 21 days after the first day of their last period.
How do you count your months in pregnancy?
