Mrs Bri everything is a movin' and a groovin' in there, so it sounds normal, your uterous tends be generally to the right hand side, so its in the right locations for the general gripes as its stretching.
If it get really painful though, its worth getting it checked out, just for the peace of mind.
I've been having round ligament pains (RLP), which are stabby. I panicked as I didnt get them until the second trimester last time, but you can get them earlier in second pregnancys. (And obviously if you are carrying extra cargo!)
It scared me shitless the first time, and I wished someone had warned me! for anyone who hasn't experienced them I've nicked this from Wiki
*The most common symptoms of RLP are:
Sudden pain in the lower abdomen, usually in the right side of the pelvic area that can extend to the groin.
Shooting abdominal pain when performing sudden movements or physical exercise. Pain is sudden, intermittent and lasts only for a few seconds.[6]
RLP may be caused by a spasm or cramp when the ligament contracts involuntarily. The ligament pulls on nerve fibers and sensitive structures of the female reproductive system. Since the uterus tends to be oriented towards the right side of the body, the pain is also often felt on the right side. This leads to frequent confusion with appendicitis.[7]
During pregnancy, the uterus expands to accommodate the growing fetus. This increase in size and weight of the uterus puts stress on the ligament that holds it, causing it to stretch. During physical exertion or sudden movements, the ligament is overly stretched, causing pain.*
