Placenta position question. FTM.

Today, I had my anatomy scan. My daughter always sits low, tucked behind my pelvic bone, which makes it difficult to see her. I see everyone with great full-frontal pictures of their baby, yet mine was barely visible on the screen. My placenta took up the screen's view. He tried every method and angle to get her to move, but she wouldn't. Is the placenta taking up her space? I'm just confused. I've never seen an ultrasound like this. The specialist didn't seem to think anything of it when I asked( or maybe he's waiting for my doctor to report the results). I'm disappointed that I wasn't able to get any pictures except one, which is barely visibly. My placenta looks huge. Can anyone explain this to me, so I can have peace of mind before next week's follow-up appointment?
