It could be a common yeast infection just follow up with your doctor and the smell should go away.
Hi!
Bad vaginal odor is commonly caused by vaginal infection or inflammation (Vaginitis) or cervical inflammation or infection (cervicitis). Both vaginitis and cervicitis can be caused by sexually transmitted diseases (STDs), such as gonorrhea and Chlamydia. Vaginal yeast infection or thrush and bacterial vaginosis (BV) are the other causes. In BV there is a distinct fishy odor. To treat vaginal odor you have to first find the cause.
Please consult your gynecologist regarding this. Take care!
