We found out what we were having at 18w5d... they said without a doubt it was a girl. She was missing all the "boy parts" so it was pretty evident that we were having a girl. Like Kele, our baby didn't cooperate until the last 5 minutes... so we weren't sure if we were going to be finding out. Good luck and I hope that you are able to see what you are having!!
We found out that we are having a little boy at our 18 week u/s. So yes they can tell as long as the little one cooperates! Phin had his legs crossed right until the end of the u/s..
Yes! You can definately see the gender of the baby at this time! That is if the little one cooperates! Good luck!
