I ve been having some pelvic discomfort for the past couple of weeks including spasms. There is unpleasant odor and I noticed I m having frequent bowel movements throughout the day. The bowel movements are small and after the bowel movement, I still have the urge to keep going. The pelvic spasms are in the middle of the pelvic, but the pelvic pain is on the left side of the pelvic. My period is late by a week and four days and this is the first time I have missed a period and not been pregnant. There is not a possibility of me having been pregnant as I have not had intercourse for the past month and a half.
