Rib pain

I have the worst stitch in my side almost like a Charlie horse. But it's a constant pain. I don't think it's the boys kicking because their hands and legs are facing each other on the inside. I'm wondering if it's just my ribs expanding orrrr... It's almost up by my bra strap and kind of toward the back. Anyone else have anything similar. Also I'm only 22 weeks. Ughhhhh😂
