Nt scan ( I’m 11 weeks 6 days) right now

Jasmine

Hello mommas, I’m a FTM and have some questions. My first appointment was last Thursday it was basically an ob orientation. Just asked me for my LMP (Last menstrual period). You know, simple questions like that. My next appointment is this Thursday for something called an Nt scan ? I know they say it’s optional but I want to do it because I want to see my baby, lol. It’d be the first time seeing him / her 💓. Can you ladies inform me on what it is exactly, did you do it? Also the doc told me to come in with full bladder? Why must I do that... thanks in advance!! Oh and was it abdominal or transvaginal?🤔
