Sharp pain right side 🙈

Hi everyone! I’m 30w & 1 day with baby number 2 and this morning I woke up and went downstairs as usual but when I came back up I had an awful stabbing pain on my right side, not abdominal area but at the side where my forearm would rest. It lasted about 30 mins and then went away. I had the same thing again as I was walking out of work, almost where I had to stop walking because it was so painful. Still experiencing it now and I finished work nearly 3 hours ago. It’s kind of come and gone and come again but it’s definitely more persistent this time. It’s definitely not round ligament pain cos I’ve had that a lot and it’s usually around the groin area and doesn’t last this long at all. Has anyone ever experienced/experiencing this? Sorry for the long post. Thank you 😘
