Upper rib pain?

I’ve been experiencing pain in this area for a little over a week now. I’m 27 weeks and 1 day. The pain is usually dull and almost feels like more on the surface than deep inside. Sometimes it feels like a pulsating numbness. It’s really hard to explain. But it’s right below where the underwire of a bra would be (I know it’s not pain from a bra because I’ve gone a couple days staying home bra-less and the pain was almost worse) and only on my right side under my breast. I’m a petite person at only 5ft2. I can’t tell if it’s a different type of round ligament pain from what I’ve felt so far or not. Anybody else feeling pain like this?
