Pregnant?

Hi all! I suffered a mc Memorial Day weekend (end of May). Then I got my period exactly one month later (although a bit shorter and lighter than usual). The weird thing is, then I had all the symptoms of ovulating shortly after my period. Now, two weeks later I am all crampy and uncomfortable in my uterine area. Could I be pregnant again or could it be some sort of problem (like tissue in there or a bladder infection)? Anyone have a similar experience?
