I am 35 years old. I have 2 kids. I stopped my delivery 6 years back. From the last 5 years I have spotting problem. menses are regular but longer than usual. Not heavy. Normal flow for 3 to 4 days. After that from 10th day to 15th day of cycle, muddy colored watery discharge like 3 or for drops. 3 months back did TVS found mild fluid in the uterus. Did pap smear it was ok. Is there any problem for concern. Kindly Suggest a treatment.
