My doctor dose not do the first ultrasound until 20 weeks. I am really impatient to see my little one before then, been browsing around and found that 3d US are about 83% accurate in finding gender between 11 and 14 weeks. I would wait till 14 /15 weeks. but do you think it's a good idea to get first ultrasound done at a private US place. Or should I wait to have first US done by my doctor. I'm concerned about anything that is abnormal possibly showing up, but have had 2 healthy pregnancies previously.
