re: whats the earliest you can find out what you're having......

17 weeks and a girl... My son I was 20 weeks.

And my doctors office would not do a 3/4D until I was at least 28 weeks! I have heard that if you ask they will like switch over for a second... but I could not set my appt until I was 28 weeks 

Quoting Penny&Jess:“ most places won't do them until you are atleast 15 weeks but I only got the 2D.....basically it was this, ... [snip!] ... and if you plan to get a 3d later on anyways it will probably have a package deal or a discount if you go back. Good luck!!”

I seen some of my friends 2ds and 3 d's they are pretty amazing. I will be 15 weeks and 1 day at the end of nov or close too it. It's sounds pretty exciting..i can't wait and i really want to find out asap..before christmas.. or i can get it done like a week before christmas.. i have heard the heartbeat only once and they said it was really good 169.. but i need to go i am feeling really really sick so nauseas right now, an dit's not going to end the way i want it to.. thank you, i'll talk to you tom.. i appreciate all of your help, i will talk to you soon

I found out at exactly 16 weeks, as did 2 of my other friends who go to the same ob!
