According to Naegele’s rule the length of pregnancy is 280 days after LMP and according to studies performed in Harvard University, duration of pregnancy in nullipare and multipare women has been respectively 288 and 283 days and according to a study performed in Oxford University it is influenced by factors such as age, parity, some illnesses and personal habits.
