Hi,
You may be having problems in the lining of the uterus including the possibility of a uterine cancer (endometrial carcinoma). This would not be picked on a PAP smear but would require a biopsy of the lining of the uterus. Please do not ignore this symptom, and remember to get yourself evaluated by an Ob/gy at the earliest,
Please remember to accept the reply if you find it useful. A BONUS and a positive rating would be duly appreciated,
regards
