My baby is measuring 4 weeks bigger....?So i had an ultrasound at 7 weeks and it gave me a due date of nov 1st..second one was 11 weeks and gave me a due date of 10/29, 19 weeks gave me a due date of 10/24....every other one since then I've measured 4 weeks ahead on ultrasound each time:(....and to add to that my ultrasound says the baby weighs 9 pounds already.. I was not a big baby, and my husband was not either.. (i was 6.5 pounds he was 7. 51/2) he is 5'9 and I'm 5'7 so why are we having a huge baby..anyone else with no history of big babies, but having them....THANK YOU..oh PS i tested negative for g.d twice but have polyhydramnios... I WAS TRYING TO ADD THIS TO THE QUESTION BUT THEY WOULDN'T LET ME:(
A pregnancy calendar is used to calculate a baby's due date. A due date calculator asks for the first day of your last period which will then calculate the number of days you are pregnant and when your baby is due to be born.
last period was February 13 and the due date is November 8 when he or she conceived?
Conception dates do not depend on the length of your period. Your due date is based on the first day of your last period. Your baby was actually conceived about 2 weeks later.
you add 280 days to a reliable first day if your last menstrual period
You might have started counting the days from when you conceived the baby, but the normal starting date is from your last missed period.
Baby due date calculators are really easy to find online. Just be sure to go to a trusted source such as webmd. Theirs can be found in the Health Tool section, under baby due date calculator. To be able to guess her due date, you will need to enter in the first date of her last period, click calculate, and an estimated date of arrival will be provided.
While predicting a woman's due date is always a bit of a guessing game (after all, baby's don't work on the same schedule we do) medical people have a formula for calculating the date based on the first day of the woman's last period. If a baby seems to be bigger or smaller than expected during prenatal checkups, the health care provider can perform an ultrasound to more accurately calculate gestational age. It's normal for the date to be off by a few days, but the only way your due date can be off by a couple of weeks would be if you were incorrect in recalling the first day of your last period.
If you can remember the date of your last period they should be able to work out your due date and from that they can work out when you conceived. However, if you can't remember the date of your last period, ultrasounds and measuring the size of your bump can be used to work out how far along you are, so you can work out roughly when you got pregnant
The approximate date of conception was April 18th 2009

A conception calendar is used to estimate when a baby was conceived. It usually uses the date of a woman's last menstrual period to estimate conception and due date.
