thank you for your query.
You could be having urinary incontinence
, however the smell you described doesnt fit in.
Yeast infection would be a thick curdy discharge, not the watery gushy kinds you describe.
The appropriate cause here could be BV or Bacterial Vaginosis
, which is also a kind of vaginal infection
, characterized by profuse, watery discharge, which typically has a fishy odour.
You need to consult a Gynecologist, and have appropriate testing alongwith swabs to pinpoint the precise infection.
Do not leave pelvic infections untreated.
