Always end up on back

I am currently 14 weeks pregnant. I know sleeping on your left side is best but I really can’t fall asleep on that side. So I end up falling asleep on my right side and transition to my left throughout the night. Lately maybe like two handfuls worth of times up on my back. It gets uncomfortable for me like a stretching muscle. Hurting my baby? I know we’re supposed to be sleeping on the left side but my body just won’t do it.
