Bed Rest - Right position

Need your advise sa tamang position ng pag bed rest. I am already 32 weeks pero too early pa for labor kaya lang short na cervix ko. I am advised na mag bed rest and take duvadillan and heragest to prevent preterm labor. I usually position sa left side pero nakakangalay. And minsan may umuumbok sa tyan ko parang si baby na stress out din or nag stretch? Any advise or encouragement will help. Thanks!
