I'm 10w 4d and they found 2 in there. I'm having twins. My first ultra sound he only seen one and heard one heart beat. Then last week I went to emergency and they found 2 babes and 2 heart beats. Just ask your doctor to take another look.
keep us posted however they should have picked up at least by the 18 week u/s... i was pregnant with identical twin boys in 07-08 and didn't find out i was having twins til my 3rd ultrasound at 14-15 weeks. but at 18 weeks surely they would have seen the baby or an extra hb, but never hurts to ask the dr anyways.
Okay thanks everyone for the help :) I'll bring it to my doctor to make sure
I new i was having twins my fist u/s because there are clearly two sacs and by 18 weeks they probably would of picked up on the extra heartbeat.
if u are having twins most of the babys hide until they are big but yes you shoul because i know all about this
Only your mothers family influences twins, and thats only for fraternal twins - identical twins are luck of the draw. However, it doesn't hurt to talk to your doctor. More than likely there's only one - they're trained to look for things out of the ordinary and while they can miss it (and I'm sure several people will post saying their uncles cousins neighbor had it happen to them) its not common.
Ultraaound techs really would have caught it. And two heartbeats as well.
