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.
It takes just 38 weeks for a fertilised egg to grow into a baby. However, we say that a human pregnancy is 40 weeks long. This is because doctors calculate the 'estimated date of delivery' of the baby from the beginning of the mother's last menstrual period - on average, two weeks before fertilisation. Only about a third of all fertilised eggs grow into a baby: most are lost before they are three weeks old.
