Hello, I'm Dr M, obgyn. You are almost done taking Flagyl for bacterial vaginosis. Some burning and vaginal redness could be related to the Flagyl. Finish the Flagyl and see what develops. Irregular bleeding wouldn't be related to BV or Flagyl. There are a number of factors with irregular vaginal bleeding including menstrual history as one.
Like I said, a number of things can produce irregular vaginal bleeding. The type of birth control needs to be considered and ovarian cysts can cause irregular bleeding. Also, is there any possibility of early pregnancy. A pelvic ultrasound is vital in assessing what's going on in the uterus and ovaries.
