I have having the 3d/4d ultrasound done in a few weeks. I want to have it done around 20 weeks but may do it later on. Has anyone had the one done where you have the early one, and then the one around 30+ weeks? I'm getting 1, I'm just not sure if I will put it off til I'm closer to 30 weeks. Can anyone tell me if the 2 were worth it, or would you just rather have had only 1. If you had both done, which one did you like better? And what week did you have yours in? gummy bear, thats so cute!! My 1st ultrasound I swear the baby looked like a little rhino, with horn and all.. lol
