Sleeping on my back!

I’m 21 weeks 5 days and this entire pregnancy including now I am only comfortable on my back!!!!! 🤷🏼‍♀️😭 I have a pregnancy pillow that goes all around both sides of me and I put a pillow on top of that at my head, BUT it’s the most comfortable position I can sleeep in!! I’ve read it’s bad for me and bad for baby so i try to start on left side and always end up on my back, and that moment I roll on my back I’m like “ahhhh 😴 “ and finally fall asleep! Bad? Good? Terrible? Thoughts?!
