Check out different websites and store! My pregnancy pillow was $55 and I felt like it was too expensive. But honestly a body pillow from target or Walmart works just the same!!! Check Amazon! (:
Just make sure you get ob chats very full of volume, the extra separation between knees will help. You don't need a fancy expensive one honestly. I got an expensive extra large one and it's way too long for me.
I used regular pillows i had in the house and rolled a big comforter to be a body pillow, cost effective as i already have an extra and works like a charm.
