Swab: Visit your OB/GYN vaginal swab/exam/HCG preg test. If you have itching/ took antibiotics around the time of your procedure it may be a yeast infection. However, it may be BV, many women are asymptomatic and don't note odor with BV and up to 1 in 5 women with BV have a yeast infection at the same time-disturbance of flora. Because you had surgery see your OB to rule out wound infection/pelvic exam
