Growing pains or round ligament pain?

I'm 10w4d with my second child and yesterday I was having pain that I can only describe as something similar I felt much further on in my pregnancy with my daughter. It was like a full, heavy feeling in my uterus. And the muscles and ligaments surrounding it were uncomfortable and painful towards the end of the day. It didn't feel like period cramps at all, but it definitely got more painful at night after I got off work. Could it be round ligament pain or growing pains this early? Or maybe my uterus rising above the pelvic bone? It just seems so early for any of these type of symptoms. Does this warrant a phone call to my doctor or is this normal?
