What is the earliest anyone has had a 3D ultrasound? I am 12 weeks 3 days, I had my first ultrasound around 10 weeks and I do not get another one due to my insurance until I am 20 weeks. So I bought a 3D ultrasound, I have an appointment to get the 3D at 15 weeks and 6 days, has anyone every had it this early before? If so, did you like it not like it, did it look weird??? I am just trying to figure out if I should do it that early, but I really want to know what the sex of the baby is, as soon as possible.
