you could go to your doctor, or local sexual health service for advice. the suppositories may have altered the balance of your vagina and this may be what is causing the smell. im asuming it is different from your usual discharge. washing downstairs with water is the best way to clean that area, avoid using soaps, wipes ect as they can often irritate the sensitive skin and make matters worse. sexual health services should be able to offer you something to restore the PH balance, for now, if you get irritation, put a hand full of salt in the bath with you, or some in a mug and wash the area, this will help to keep it clean and free of infection. also make sure you dry it properly.
