you can get a blood test to find out sooner but via sono you can't even tell until 13 ish weeks and most doctors won't confirm it until 18 or after because it could still change.. my doctor does it at 18 weeks so I still have 3 more weeks if baby cooperates
@scoobygirl30, Yes, I went to a 3D ultrasound place though, where you pay for it and your insurance doesn't. It's not related to any doctor at all it's just got fun. Quite pricy but worth it!
