For Various Health Issues I Have Been Prescribed A Bacterial

for various health issues I have been prescribed a bacterial fighting antibiotic 3 times over the past couple of months. Once for sinus infection, once for possibility of bladder infection following surgery and now for a bleeding breast. I feel as if I may have a vaginal infection and have used canestin 3 day. I am still not feeling back to normal. is it normal for me to have this problem after taking that much antibiotic in that short period of time?5
