Following thepublication of theCanadian Post-term Pregnancy Trial  and the Cochrane Review on Post-term Pregnancy Management  the Society of Obstetricians and Gynaecologists of Canada issued a clinical practice guideline  recommending that:
1 After 41 weeks' gestation, if the dates are certain, women should be offered elective delivery.
2 If the cervix is unfavourable, cervical ripening should be undertaken.
3 If expectant management is chosen, assessment of fetal health should be initiated.
The Royal College of Obstetricians and Gynaecologists (RCOG) issued a clinical guideline on induction of labour in 2001, which included recommendations on management of prolonged pregnancy . These recommendations were:
• An ultrasound to confirm gestation should be offered prior to 20 weeks, as this reduces the need for induction for perceived post-term pregnancy.
• Women with uncomplicated pregnancies should be offered induction of labour beyond 41 weeks.
• From 42 weeks, women who decline induction of labour should be offered increased antenatal monitoring, consisting of a twice weekly CTG and ultrasound estimation of maximum amniotic pool depth.
The American College of Obstetricians and Gynecologists Practice Guidelines  are at considerable variance with those issued by RCOG and SOGC.

The first trimester is very important for the mother and the baby. For most women it is common to find out about their pregnancy after they have missed their menstrual cycle. Since, not all women note their menstrual cycle and dates of intercourse, it may cause slight confusion about the exact date of conception. That is why most women find out that they are pregnant only after one month of pregnancy.
