You should go back to the doctor for a follow up after like a week or so.

If you take every single pill the way you were directed to take it; it should get rid of the bacteria. But if you dont finish it or as directed your just giving it a better chance of living and multiplying even if you dont take one pill a few bacteria can live. They multiply about every 15min and in a matter of hours go back to the same strength of what they were in the first place!

Just remember to take all of your meds the right way!!
