Hi,
Welcome to ehealthforum,
Your symptoms are suggestive of infection (vaginitis, or vulvovaginitis, bacterial vaginosis or fungal infection, etc). You should consider going ahead with visiting your doctor/gynecologist for examination and vaginal swab/smear test to identify the causative agent and get started on appropriate treatment. Get your partner also treated simultaneously to prevent chances of re-infection. Avoid having intercourse while being on treatment or use additional protection if having intercourse while being on medications to continue to have protection from your birth control. Drink plenty of water.
Take care.
