Upper right side, near the rib cage? I recommend seeing your doctor. It could be your gall bladder or liver. As for ovulating, I think there are tests on the market for that now. Didn't have those back in my day :-) Please don't ignore the pain. Get it checked. Take care.
add on to previous question....also having a heavy and fullness on the right side. trying to conceive. my cycle is 29- 30 days. how do i find out if i am still ovulating.
