Plus sized mamas

This is very embarrassing but I have my first scan coming up, I’ll be 12 weeks. I’ve never been skinny and although I have lost a lot of weight I have an ‘apron’ stomach (just very flabby from the weight loss). I now weigh 138 pounds. Do you think they’ll be able to see my baby from the scan or will I likely need a transvaginal ultrasound? I’m just trying to prepare myself. If it’s a ‘normal’ scan will I need to lift my apron stomach up? Any feedback or tips would be much appreciated. I have a lot of body struggles so I’m pretty worried about it,
