Help is this normal?

So before I was pregnant my boobs weren’t that big at all, and I’m about 11 weeks and obviously my boobs have grown a bit but not like huge and they’re more sore and hard. But when I lay on my side they like crush together and it feels like it’s harder to breathe or I have to take bigger breaths like my breathing is almost restricted. And if I sleep with my arm that isn’t underneath my body, it feels like my ribs are hurting 😂😂😂 but if I sleep on my back I’m totally fine. it’s giving me a little anxiety is this normal
