Hi welcome to Health care magic forum.
Thanks for calling H.C.M.F.
As you describe You have clear discharge, sticky with no smell. Recently it became orange colored and had lower abdominal pain
, Discomfert in sex,Many S.T.D.tests were negetive, You had treatment with antibiotics once in a month , no ovarian cysts found.
Due to treatment with antibiotics several times,there could be yeast infection, which might be causing all these symptoms.Other causes might be harmones imbalance due to any reason.
I advise you to consult an endocrinologist
for diagnosis and treatment, You may have to undergo harmones essay besides other routine tests for confirmation .
