Einstein Von Brainstorm Posted January 29, 2016 Posted January 29, 2016 I somehow started an argument about the human gestation and then went to bed last night - I apologise! A baby is considered 'full term' at 40 weeks. 7 days x 40 = 280 /by average no of days in a month = 9.3 months which is closer to 10 months than 9 A baby born between 36 - 40 weeks is considered 'normal' so some women are pregnant for closer to 8 months, some are pregnant for closer to 10. In the UK they won't let you go past 42 weeks pregnant without induction. Which is why people say 9 months pregnant as that is the average expected pregnancy length. Where we live the midwife takes the first day of your last period and counts 40 weeks from that date as your 'due date' even if the ultrasound later tells you different your pregnancy file keeps the original calculated estimated due date (EDD) so you are considered to be 1 month pregnant as soon as you miss a period. Where my Mother and Sisters live they don't give you an EDD until you have had a dating scan. Scans (where we live) are done at 12 and 20 weeks gestation, no 9 week scan or dating scan. You only get additional scans if there is an issue they need to keep an eye on. Our maternity hospital have also stopped estimating the sex of the child so private ultrasound businesses are booming here. As our NHS uses the midwife count and not the ultrasound date, all 3 of our kids were considered to be premature despite all being just under/over 9lbs in weight and 52cm (around 20 inches) long. TL;DR different countries/medical practitioners do things differently. Average pregnancy falls somewhere between 8 and 10 months. Congratulations everyone is right!
