First time baby here, do all ultrasound machines in offices like at your 18/20 week scan have the ability to go into 3d or 4d mode ? I know you mostly have to pay for those things but I was wondering if any ladies just asked for them to switch it to that.. and they actually did ? Or is the gender scan already in 3d ? I’m not sure how this works .. I’m sure it’s probably different every place but my gender (18 week) scan is next week & im wondering if it’ll be just 2D & they check that area or 3d ?
