Pain on my left side on the ribs

Hi,

I am 28 weeks 2 days and yesterday and today I have pain on my left side on my rib cage. Has this happened to anyone else. Just the left not the right. It is sensitive to the touch and hurts a little if I move a certain way or when I shift at night. No weird spotting or anything at all other than that. I’m guessing it could either be from a baby kicking or maybe her position. First pregnancy and this didn’t happen to any of my friends. Just wondering if anyone else has experienced this!
