Hi Gorgette,
Its pretty normal for your joints to get more flexible because hormones soften up the ligaments or something but maybe watch out for too much swelling. Cant tell u enough, if your already having accidents when you sneeze, keep up the pelvic floor exercises or it will get worse. My health nurse reminded me the other day to keep them up or otherwise I will be wetting my pants at 40. Lovely lady!! The joys of child birth hey?!!
