Hi, not sure about amniotic fluid, but as for the head part, I suggest to walk as much as u can! It’ll be easier during birth as well. I didn’t walk much during mine, and when my water broke, baby was still high up. So my labour was longer, and I had to push even harder. My nurse told me to push harder else they will have to csect. But I did manage to do natural. Just that it’s harder I guess. More energy, more effort.
