First Ultrasound: Concerns About Limb Development at 12 Weeks?

Question
Hi!  I just turned 12 weeks and had my first ultrasound today.  The baby has not yet deloved normal arms, hands and fingers.  The person doing the ultrasound called them arm buds.  The baby was moving them quite a bit.  At the time, I didn't think anything of it, because this is my first child.  After, I got home... I read online that babies limbs should be developed by now.  Do you think this is something to worry about?  Any help would be greatly appreciated.  Thank you!

Hello Nicole. I think the u/s technician is just used to describing the body parts in those terms. Once again, a scan has caused anxiety needlessly. I do NOT support U/S scans for ANY other reason that emergency situations. They are VERY inaccurate for most of the things they are supposed to be used for. Please consider refusing all further scans unless you are bleeding! If indeed there is something amiss, your dr will have a report at your next visit- I don't think you have anything to worry about. All the best- cheri.
