A multiple pregnancy involves more than one offspring, such as with twins. Pregnancy can occur by sexual intercourse or assisted reproductive technology. It usually lasts around 40 weeks from the last menstrual period (LMP) and ends in childbirth. This is just over 9 lunar months, where each month is about 29Â½ days.
How long a healthy pregnancy lasts can vary by as much as five weeks, even when doctors precisely determined the date of conception, a new study suggests. Although the length of a healthy pregnancy is known to be variable, some of this variation was thought to be due to errors in determining the age of the baby, the researchers said.
