Pregnancy sleeping position

I’m almost 37 weeks pregnant and have been sleeping on my sides since I was about 12 weeks however pains in my shoulder blades and collar bones which is causing me to not be able to sleep it’s currently 9:38am and I’ve had not a wink of sleep due to this I’ve tried everything and I’ve googled good ways to sleep if this happens and that just says on your back but I can’t do that as it’s dangerous for baby I’m just wondering does anyone have any suggestions because I’m really worn out before baby is even here
