Confused

Queen girl

So today was my 36 appointment and my doctor checked my cervix and said I was 1cm dilated but my baby is still high after my appointment I had an ultrasound as well the tech told me that she wasn’t able to give me a picture of the baby face because he was very low. I don’t understand because one minute I’m told he’s high and the next minute I’m told he’s low. What exactly does it mean?
