Ok so I am a first time mommy and I have been looking at ultrasounds all over. I know there are two different kinds. I am just wondering what is the difference between the two? I know one they go inside and one is just done on your abdomen but besides that is there any difference? I feel like the ones I've seen that are abdominal are less vivid and clear. I'm just afraid they'll do abdominal and I won't get a clear picture of my baby! Anyone know if you can request one over the other? Sorry for all the questions!
