3D - 2

3d ultra sound place told me im measuring almost 3 weeks small?

so im sixteen weeks along and my dr did an ultrasound at 8 weeks and the baby was right on target she did this to get a better due date idea even tho i know the exact date of last period she wanted to check. she has been doing the outside measurements and also said im righton. today i went to a 3d place to find out the sex of the baby and they told me that im only 13 weeks going by the size of the baby. has this ever happened to anyone?? who should i go by on my due date the dr says oct 25 the 3d place said nov 11. i do have a ultrasound with my doctor already lined up for june 8th but im a little worried that someone is way off

1. This happened to my sister in law just a couple of weeks ago, and she ended up losing the baby. I don't want to scare you but she was 22 weeks along, and the baby was fine, but she went and they said she was measuring at 19 weeks and then a week and a half later she had a still born baby. I would go to your doctor again, and make sure they check things out. My sister in law they think was having blood clots (undetected) and so that is why the baby was small. Not getting enought blood and such. Just be careful, you should talk to your doctor about it. Good Luck I hope everything turns out safe and sound for you!
2. this happened to me. 3/4 way through ,my pregnancy they told me i was 2 weeks smaller. my son was 10 early to the later date. the first date was much closer to the target.
3. Your doctor is probably more accurate than the 3d place and early ultrasounds are the best way to tell a due date. I would go by your doctor's due date but it was good of you to set up another ultrasound just in case.
4. the opposite happened to me. he was always measuring weeks ahead. well, he came out a week late and was 10 lbs. so he was just a big baby. you are probably either having a smaller baby or they could just be off. they told me so many friggin due dates. i dont think they are very accurate
