hi there, at 33 years of age it is unlikely that you are experiencing premenopausal symptoms, you are not pregnant so along with
weight loss,
irregular periods and foul smelling discharge,it sounds ominous and you will require a thorough work up. Kindly get your blood workup done along with abdominal
ultrasound, a PAP smear examination and a gynac consult. It could be anything from
pelvic inflammatory disease to malignancy and so you need to be vigilant and get to the root cause. Take care.
