The most accurate way of detemining the due date is based on your last monthly period, verified with an early ultrasound (prior to 10 weeks). They are usually pretty accurate within 2 weeks.

Doctors are only human. Your due date is the date that is given to you of when you can expect to go into labor. The dates are not usually very accurate. More often women go into labor with 2 weeks of the expected due date.
The most accurate way to determine a due date is when the woman knows the day of conception. This rarely happens so normally due dates are determined by using the 1st day of the woman’s last period. Normally the total gestation time is added to the 1st day of the last period minus 2 weeks.
They count by the weeks by the first day of your last menstrual cycle.
Babies come when they want to. The doctor is only "guesstimating."

Usually yes. The early ultrasound (around 8 to 10 weeks) is usually the most accurate predictor.
There are however exceptions to every rule. The doc told my sister she was due July 26th, the ultrasound said 8/28... the ultrasound was the correct one.
Good luck

As far as the Level 2 ultrasound I had, the baby's measurements measure out for me to be abt. 5 or 6 days more than I am. I told my doc. He said just stick with what we talked about. I'm due 3/26. So I'm assuming sometime in March I'll have her.

Yes an older Dr's estimations can be pretty accurate. Before ultrasounds etc... your Dr. would measure from the symphisis pubis (middle of pelvis bone anteriorly) to the fundus (top) of the uterus in centimeters.
That measurement in cm. is pretty faithful to actual weeks of pregnancy.
Let's say at the umbilicus (navel) in a pregnant woman ; measuring from the pubis to the umbilicus flatly (holding tape measure agains the skin) that measurement would be m/m 20 cm that corresponds to twenty weeks .
All these measurements have a plus or minus two week margin of error.

Hmm..I'm not sure
I couldnt remember my last period [still can't] so the doctor said he couldnt give me an accurate date. He said he thought i was about 14 weeks. The next day, my midwife felt my belly and used the heart monitor on my baby and said she thought i was about 18-19 weeks.
I had a scan 3 days later and they said i was 16 weeks.
So i'm going by my ultrasound date...
By my ulstrasound date im now 27 weeks pregnant.
I THINK LMAO

Once you have an Ultrasound it is prity acurate. They do a messurment of the baby and are prity right on. My baby came 3 days early

Within a 10 day span, they're pretty accurate, and a scan helps too. However, if it's your first baby or your third can also change the delivery timing.
Maybe you just don't have confidence in your doc, so change him/her. Peace of mind in the mother will help the infant a lot.

The measurement of the ultrasound is the best judge of due date and how far along you are.
