A foul smelling vaginal discharge
usually indicates either a bacterial or a fungal infection
. And it depends on your personal hygiene. In regard to your irregular periods
, I would suggest a visit to your local gynecologist where they would probably advise hormonal studies such as your thyroid profile, estrogen and progesterone
levels. And also in your case of vaginal discharge, your physician might do a PAP smear which will be sent to a cytopathologist to evaluate what type of infection you may be harboring.
