Hello, i've missed my period by about 9 days.. also, i have a sweet smelling vagina and no discharge but my minor vulva was itchy for 4 days?

Depends: Many things can cause a missed period. If you are sexually active then consider a home pregnancy test and follow up with a gynecologist. Itching can also be caused by many different reasons. The hormonal chanes including those from pregnancy can increase risk of yeast. I would recommend gyn evaluation to be sure. You could try over the counter clotrimazole cream and if not better see dr
