I remember round ligament pain being lower, near the pelvis, that is where the ligament attaches. If I remember right, I was having a similar feeling. The doctor told me in my case it was nothing unless . . .(don't remember the actual symptoms). If I was feeling those other symptoms then it could be spleen or gallbladder issues or something like that. In other words, it is probably nothing (maybe baby kicking you hard), but talk to your doctor soon just in case (call him if your next appointment is more than a week or two out).
