So first of all this is an estimate of when your baby will come. Only around 5% of babies are born on their due date with most being born a week either side. A normal pregnancy lasts between 38 and 42 weeks. This method of working out the due date from the date is called the Naegele method and was developed in the 19th century. It is based on the assumption that all women have a cycle of 28 days and will then ovulate on day 14 of their cycle. Some believe that pregnancy duration is linked to the length of your menstrual cycle so the longer the time between periods the longer you will be pregnant for. That is why it is called EDD or Estimated Due Date as we just can’t tell when your baby will arrive. Maybe we should do what the Ugandans do and have an Estimated Due Month!
So what causes labour? Well it is believed to be the body’s response to hormones released by the baby. These start to soften the cervix and cause the uterus to contract. Now if you are feeling fed up with being pregnant, not being able to were clothes with a buttoned waistband, the heartburn or you just want your body back then induction – natural or medical may be something you should want to consider.
