I'm 23 years old, unmarried women, I am experiencing pain in my lower abdomen since last 8 months. The pain typically occurs after my menses and lasts uptill mid cycle and then it normalizes. The pain is localised to both sides right and left in pelvic region, sometimes it radiates to legs and lower back. The pain is cramps and dull type like it occurs in menses. In the last cycle the pain started 2-3 days early before my menses decreased during menses and then started again after 6 days. The pain is increasing in intensity in successive cycles. I'm not constipated, my bowel bladder habits are regular. I don't have any digestion problems. There is no aggravating and relieving factors. On 2 episodes I noticed my urine to be brownish in colour, it was painless and I don't remember the timing it occurred. I also noticed I have less bleeding since 6-7 months, I have 6 days of bleeding during menses but now I have bleeding only 2 days after that very scanty bleeding till day 6. Kindly help! I have done a usg scan it shows normal ovaries but mild fluid collection in pouch of douglas. Doctors said everything is normal. Kindly help as I don't think it's normal.
