With my son I was measuring 3 weeks ahead at one point. At 38 weeks I was measuring 41 and I went into labor. He was a big boy though. The last few weeks of pregnancy I was always measuring ahead. But unless it's off by a lot, they don't usually worry. You could go before your due date but it always depends!
Okay that's good, I just don't want him to get TOO big and going over the time he should be in there affecting him at all.
I am also measuring 3 weeks ahead, I think it is pretty normal to measure a little off. My sister was measuring 4 weeks ahead and didn't give birth until 5 days before her DD.
Don't feel bad. I'm 34wks and measuring 41cm.
I saw your question and looked this up for you, i hope it helps
How is my baby's growth measured during pregnancy?
Starting at about 20 weeks, at each of your prenatal visits, your healthcare practitioner will measure your fundal height — the distance from your pubic bone to the top of your uterus. This measurement allows her to assess your baby's size, growth rate, and position. As a rule of thumb, your fundal height (in centimeters) should roughly equal the number of weeks you're pregnant. For example, at 20 weeks, your fundal height should be about 18 to 22 centimeters.
What does it mean if I'm "measuring large for dates"?
Measuring large for dates means your fundal height is more than 2 centimeters larger than average for your stage of pregnancy, based on your due date. Your practitioner will probably schedule an ultrasound to find out why. Among the possible explanations are:
• Your due date is off. (The ultrasound can help your practitioner figure out your correct due date.)
• You have looser abdominal muscles than most women as a result of an earlier pregnancy.
• You have uterine fibroids.
• You're carrying twins or more.
• You have too much amniotic fluid.
• Your baby is positioned high above your pelvis, which might be the case with a breech baby or if you have a placenta previa.
• You have a bigger-than-normal baby because of gestational diabetes. This condition is known as macrosomia. You may need to be tested to rule it out.
Or you might simply be carrying a big, perfectly healthy baby.
