ISN’T IT TEN MONTHS?
Q: I’m 13 weeks pregnant with my first baby. I’m so excited, but I need to know how long does a normal pregnancy take? We grew up knowing it’s nine months, the magazines say it’s 40 weeks (on counting that’s 10 months!) but the doctors say the baby will come when it’s ready. I went to the clinic and met other pregnant moms. One was complaining that she went to see the doctor because she was due – she was 40 weeks and three days – but the doctor said she still had another month to go. Also, are the ultrasound scans accurate when estimating due dates?
A: Tina says: Many moms-to-be are confused about how a pregnancy is dated. A pregnancy lasts between 266 and 280 days. Medical staff tend to talk about pregnancy in weeks – and 40 weeks is considered normal. I know it sounds as if that means a pregnancy is 10 months, but remember a lunar month is not only 28 days, but as long as 31 days in many instances. So the 10 months of pregnancy measure out to be (more or less) the same as the nine months of the calendar. In most cases the most accurate scan date is the date you get from your very first scan. Hope this helps.
