Thanks for posting on HCM
From the look of things you are probably having a post-abortive infection or septic abortion
. Free fluid in douglas' pouch on USG simply signify that you have a pelvic infection
which will of course require a course of antibiotics ( you just follow through you doctor's directive). As for the repeat D&C, not very sure if it is useful except of course you are presenting with vaginal bleeding (which is the main sign of retained products of conception or uterine atony
). To me, your doctor could just hold on a little, treat the infection and see if the USG signs clear off.
Hope this helps
