Talk to Gastroenterologist on H Pylori Symptoms Are Not Going Away

Hello Dr, I was tested positive for H Pylori back in July, I went to Dr and he prescribed me antibiotics with PPI. I completed 7 day therapy but it was not much effective so, I got retested after 3 weeks for H pylori stool test it came back positive, then again I got 14 days triple therapy including Amoxicillin 250mg BD, Clarithromycin 250mg BD, Risek 40mg. I completed the course but the symptoms are not going away, sometimes stomach pain, sometimes irregular bowel movement, sometimes it looks like something stuck in my throat, I have lost weight and eat little because I feel no hunger.. anyone please suggest me what to do. I'm really stressed out.
