Digestion Issue. Any changes are needed?

Hello Doctor, I have been experiencing mild discomfort above my belly button along with acid reflux and frequent burping. Initially, I was advised to take Rifagut 550 and Econorm, and was asked to do stool and blood tests, including amylase, along with an abdominal ultrasound. All the reports have come back normal. Since yesterday, I have been advised to take Sompraz 40 and Bifilac. However, I haven’t noticed much relief yet. I am currently breastfeeding, so I’m a little concerned about the safety of these medications. Could you please confirm whether Sompraz 40 and Bifilac are safe to take while breastfeeding, and whether I should continue with the same medications or if any changes are needed? I’m a bit worried about the ongoing discomfort. Please advise.
