Hi when I have sexual intercourse with my partner I have bad odor even with the condom. I am worried. Went to the gyn three weeks ago and she gave me terazol (terconazole)?

B. vag. Bacterial vaginosis is the most likely diagnosis. It is not an std, but a condition caused by a decrease in vaginal acidity. Flagyl or Metrogel is the treatment. Revisit a doctor.
Likely bacterial. A "fishy"type of odor is known as bacterial vaginosis. It's from bacteria from the ad place testing into the good place and colonizing. The antibiotic for this is metronizadole 500 mg 2x per day. It will target the bacteria. Look up bacterial vaginosis, stop wearing a thong if u do, and an occasional dilute vinegar douch can help. Don't use a lot of pressure b/c you can push germs into uterus.
