In your case, the fluid in the pouch of douglas could be suggestive of pelvic inflammatory disease
. This is an infection of the pelvic organs like uterus, fallopian tubes and ovaries. The resultant inflammation leads to an accumulation of fluid in POD.
You will need a course of antibiotics like metronidazole
, doxycycline and ciprofloxacin
Please see a physician as soon as possible as this infection can impair your fertility
if left untreated.
Hope this helps.
