Try a body pillow and some benadryl it worked for me! My doctor said the benadryl is perfectly safe hopes it gets better for you!
I have a body pillow but no luck :( plus my partner is so awkward when he sleeps I get elbows in my back the lot he's tried sleeping in the spare room but still no luck as I cant sleep with out him with me :(
I'm ten weeks as well I jus bought a body pillow yesterday and no luck either they say its jus the pregnancy hormones :/
