im a 17 year old, sexually active girl. as of late i was diagnosed with a UTI (urinary tract infection). i was put on an anti-bacterial medecine, i didnt take one day of the medecine, went back for my check up and found out i still had it. so now im back on the medecine. this time around, ive got the worst yeast infection ever, the itching is unbearable. ive read that antibacterial and birth control pills can cause yeast infections. are there any tips out there so this wont happen again? ive got my cranberry juice and yogurt loaded up. any tips will be most appreciative.
