Burning-like sensation

Brienne

I don’t really know how to describe it, but the last 20 minutes or so I’ve been having this burning sensation in my uterus area. Between my belly button and pubic bone. I wouldn’t even call it cramps since they’re can feel different to different people. I also feel a fullness in my uterus area. I’m currently 6+4. This isn’t my first rodeo but I don’t remember feeling this. It’s more of a discomfort than painful. I took some Tylenol and am currently waiting for it to kick in. About to take a warm bath. No bleeding or anything either. Could it be round ligament pains? This early?
