Hpylori infection recovery time. This?

I had severe lack of appetite and nausea and occasional green stool (once every 2-3 days, other days stool is normal color) around a month ago and got an endoscopy+colonoscopy done to test. It was confirmed that I had a h pylori infection. The doctor prescribed rifagut 400 for 7 days, 2 tabs a day along with vsl#3, nexpro it and meva sr 200. I finished the course and saw some improvement in my symptoms. Then the doctor asked me to continue nexpro it and meva sr for 15 days. Additionally, I had mild constipation so the doctor asked me to take cremaffin plus 10ml for 10 days at night. However after a week of finishing rifagut, symptoms returned and I got a stool test done which showed that I had ecoli as well. The doctor then prescribed 5 days of ciplox 500, 2 tabs a day. I finished this course as well but I still face the original symptoms. Any suggestions as to what to do next? Is it possible that hpylori still hasn't been eradicated which is the reason for all this?
