Hello and welcome to HCM,
Presence of pain abdomen and discharge are suggestive of pelvic inflammatory disease
The increase in amount of discharge after intercourse is also a characteristic of PIDs.
Consult your gynecologist for clinical examination, investigation (ultrasound
abdomen, examination of the discharge, and / or endometrial biopsy
Once confirmed the infection can be cleared with appropriate antibiotics.
Thanks and take care
Dr Shailja P Wahal
