Heavy gals - tell me about ultrasounds.

I've only been overweight for about 2-3 years. I'm wondering how an ultrasound goes when you've got extra padding in the abdomen. I have worried visions of embarrassingly having to move my body weight around or the over dramatic "we can't see your baby because you're just too fat" (not that anyone would actually say that... hopefully). My body changes before pregnancy and since (boobs and bloat) have me feeling very insecure atm.

So tell me its going to be okay right?
