Sleeping on my back/Lying on my back

Hi I’m 32 weeks today. And I noticed that I try to sleep on my left side but I wake up lying on my back. Sometimes I sleep so comfortably on my back I’ve read so many horrible effects that can happen but I can’t seem to control it. I don’t have anyone beside me to wake me up and tell me to face left again. I already tucked myself with so many pillows but I end up lying on my back.

Are there other people experiencing this? Is it really that bad? I hope my baby’s fine. First time mom and probably will be a single parent.
