Sleeping the "right" way?

Every night I lay & fall asleep on my left side because I heard it's the best side to sleep on while pregnant for the baby. But most times I find myself laying on my back or on my right side not knowing how long I was laying that way. FTM here and I do get worries . Does it truly matter how I sleep? I'm 27 weeks + 4 days pregnant. My baby is an active one but I just want what's best for her while she's still developing.
