Anyone else struggling to sleep at night?

I really don’t know what it is but every night for the past week I just can’t sleep, I can’t get comfortable and I’m not that big yet I’m only 19 weeks. I just lay there all night tossing and turning, I can only get comfy on my back and we shouldn’t sleep on our back 😭😭😭 plus I feel like my bump goes really tight at night so that worries me too 😭
