Stomach ache/discomfort. Is needed?

2 weeks back I had taken a course of amoxyclav for my tooth infection along with vizylac rich capsule(twice a day) for 5 days since then that I am having stomach discomfort, initially it fet like gas inside stomach, the slowly i had pain in the centre stomach area. My stool are normal but i see pale yellowish colour sometimes. 4-5 days back i had stomach ache before sleeping, the next day I consulted a doctor via practo and he prescribed me this, since last 2-3 days i am on the medicines attached in the images. Symptoms i have now: After eating today i fet a little ache in the central area, then when i was outside before dinner it felt like air/gas, the pain that i used to have before sleeping is not there, Still sometime i feel slight(2/10) nauseous and I don't feel fresh. Please help me out, should I continue with the medicines or change is needed?
