I'm really conscious of this as I love to sleep on my back & am finding it very hard to turn from side to side - keep waking myself up. Also, this lunchtime I had my eyebrows done & had to lie on one of those beauticians' couches (I was on a slight slant from about the middle of my back upwards) & am now paranoid that I have starved my baby of vital oxygen & irreparably damaged it...(I'm 20wks pg). Anyone out there less ignorant than me?
