Sleeping on the right side

So I’ve always slept mainly on my right side, but today I came across an article saying that sleeping on your right side increases your chance of stillbirth. Honestly this is the only time I’ve heard this and I know you can’t believe everything you read online but I’d like to know if anyone else has heard this before. I’ll definitely try hard to sleep more on my left side but once I’m asleep it’s kinda hard to stop from rolling over.
