They normally adjust ur due date off the 1st ultrasound done before 20 weeks. At least my doctor does.
The ultrasound tech since she's going off the size of the baby.
Thanks that's what I thought so Feb 17 is my due day then
Your baby can be born anywhere between weeks 38-42 and be normal. The due date just gives you an idea, but most women don't deliver on their due date.
I wouldn't read too much into the exact date. Just know you'll most likely deliver in February.
After a certain point in pregnancy babies growth changes from pregnancy to pregnancy which I why the first ultrasound early on in the pregnancy is the most accurate. It is just an estimate your doctor is the one who ultimately decides whether or not the date should be adjusted.
Its only a few days off from the original date doctors don't like to change it unless its a week or more.
