Ive been diagnosed with gerd/gallstones i was on medication for one month but i still get symptoms i burp a lot and pass a lot of gas with chest pains?

Address the causes: Not surprising as those meds don't address the causes.Many docs would advise removing the gallbladder but it's possible to shrink or pass the stones- see https://draxe.com/health/gallstones/ and https://www.ener-chi.com/books/the-amazing-liver-gallbladder-flush/ For GERD see https://chriskresser.com/what-everybody-ought-to-know-but-doesnt-about-heartburn-gerd/ and try melatonin 6 mg at bedtime.
