Hi, many thanks for the query!
Well, everything that is going on is ok, diarrhoea
may be as a side effect of medicines that you are taking, just do stool (culture & sensitivity).
Also, get USG (Abdo-Pelvis) & RFT done.
Change antibiotics as per the report of culture & sensitivity if needed with your doctor's opinion.
Drink plenty of water (preferably ORS
Wish you a good health.
