I am 25weeks and measure 31weeks but my doctor won't change my due date why?

Question

Ultra sound measures baby with grow @ 31 weeks, No I am not fat

Answer 1

Doctors can be stubborn sometimes. when i was pregnant with twins 32 years ago, I had a female doctor in the States tell me that I was not due until the end of January, and that if I went into labor before the middle of the month she would stop the contractions. The twins were born in France and I was actually a week over due. The female doctor was basing things on uterine measurements and the date of my last menstrual period, and did not take into account that I have a wider then normal uterus, and that I had a period during the first month of pregnancy.

Another reason could be that the baby is big for his/her gestational age.

Answer 2

The only thing you can really do is talk to your doctor about it. Nobody here can give you a for sure answer.

My LMP said I was 18 weeks, and when I had an ultrasound and measured 20 weeks, my doctor did change my due date.

The only reason that I can think of is that since you are further along now, babies grow at different rates. You might just have a larger baby. If you had measured farther along earlier in your pregnancy, then he/she probably would have changed your due date. But now, because your far enough along that your baby could just be a bigger baby, it's less likely that your farther along.

Good luck and you really should ask your doctor about this. That's why he/she is there, to answer your questions!

Answer 3

He's probably seen your ultrasound results and your baby is probably just a large baby; by ultrasound you can see whether your baby has developed and/or measures up to either 25 or 31 weeks.

You might have some extra weight around the middle pushing your baby belly out more... no offense of course. I only put on 25 pounds in my pregnancy and it was all baby, I was back to my prepreggers weight 2 weeks after delivery. Anything more might also impact what you measure.

Answer 4

I have a friend who measured a month ahead for most of her pregnancy. She is now at 35 weeks and everything is lining up for her exact due date. In other words, her measurements finally caught up to her EDD. So, don't worry. You are still really early and you don't want to have a premie with tons of complications. Size isn't the important factor, the development of the baby is. Lungs take a while to make. Give it time. GOOD LUCK.

Answer 5

The rate at which the baby grows changes over the course of the pregnancy so doctors tend to calculate based on lmp or an early ultrasound rather then a later ultrasound.

Answer 6

Because if they changed it to 31 weeks and the baby really wasn't developed that far... your baby could be born premature and have certain complications. There is no harm in waiting it out, be better for you both all the way around.

Answer 7

Measuring how--your tummy, your uterus, the baby, what?

Your doctor wants to hold off and make sure everything is in order. Do you have diabetes? Is this your second child?

There is no normal with fetus size. Some are larger, some are smaller.

I would just trust your doctor.

Answer 8

Don't worry, nothing the doctor writes on a file is going to change when the baby actually comes - that decision belongs 100% to your baby.

Answer 9

you might measure 31, the baby could be big but still needs to develop further, why aren't you asking the doctor this question?

Answer 10

Because I think the babies lungs are not fully developed until week 37, and he probably wants to see if you are going to get bigger. If not than your due date can stay the same. Good luck
