Ribs hurt!

I’m 19 weeks and 1 day and my ribs have been hurting for about 3 weeks and seem to be getting worse. It’s hard to sleep on my sides. It’s just uncomfortable in general. I’m 5 4” so I’m thinking it’s because I have a shorter torso and not much room for baby or it’s because everything is stretching. Didnt think I’d feel this till third trimester. Anyone else experiencing this?
