I Have Been On Antibiotics For Almost A Month Now...just

I have been on antibiotics for almost a month now...just had 2 teeth extracted yesterday morning...one of the ER Dr.'s gave me diflucan to take the last day of the antibiotics and I have had a vaginal discharge for over a week now...I have had a complete hysterectomy over 10 yrs ago and have never really had problems with any discharge like this...is this normal reaction to the diflucan I took or do I need to be rechecked...
