Inflammation of cartilage between ribs making it harder to breathe?

I’m 33 weeks now and for the last month I’ve been getting Braxton Hicks which has been putting pressure on my chest and making it feel harder to breathe properly, I eventually got told I have inflammation between my ribs and every time the Braxton Hicks happen it pushes the diaphragm up causing pressure on my chest. I’m really worried that this will be 10x worse when it comes to actual labour contractions, has anyone else had this?
