Tips for transitioning from being a lifetime tummy sleeper?

Mi

I’m only 5 weeks, but I’m so particular about sleeping on my stomach with one leg straight and one leg bent up! Have been my whole life so I know transitioning will be a struggle.. Want to start trying to get used to sleeping on my side ASAP. If you ladies have any helpful suggestions, brands of pregnancy pillows, etc. that would be super helpful! ☺️💕
