Talk to Gynecologist on Pain Under Breast/ Rib- Pregnancy

I have pain under my right breast or maybe it’s the rib cage I’m not quite sure but i had this in the early days of my pregnancy too, the area would feel tender to touch when pressed or stretched then the pain eventually subsided, now I’m having it again in my 2nd trimester since almost my 20 weeks, I’m currently 27 weeks. The pain is now making it difficult to sleep on the right side and also causes difficulty in breathing sometimes. It’s a dull constant pain, i also feel it while bending or wearing something tight. My dr isn’t paying attention to it much pls help me what exactly is this and how do I treat it?
