I am doing the 3-D at 16 weeks. You can tell earlier, but the u/s place I am going to said at 16 weeks they make cute facial expressions and stuff. I want to do the gender thing plus pics, so it works out great. The only "proof" I need is my u/s pics from my last appt because they want to make sure I am seeing a doctor. Like the other ladies said different places say different things. Mine is mainly gender determination.
