Have you got a v pillow Hun? I find the best way is to put a pillow flat down one slightly higher up on top of that one then your v pillow over the top! That way you have your back supported (as I have had back pain from laying) and your in a good position where you won’t really be able to move, sounds horrible but you need to be up in that position so you don’t damage anything!
It’s easier than it seems, don’t worry!
Also if you are travelling by car take your pillow/ v pillow with you for comfort!
Good luck
