HPylori Infection

Hi I have been identified with Hpylori after some months of trouble and my doctors suggest antibiotics (2 + 1 ppi) but 2 courses are done still with my last stool test the result came as positive for HPylori.

Now my doctor has suggested a 3rd course of antibiotics and i am going to start it tomorrow. Kindly suggest if its normal or we are missing something here or should i consider something here?

Thanks
