Eh perut bunyi tu mmg normal je, lagi-lagi kalau bukan sebab lapar, biasanya tu just gas moving around atau digestive system doing its thing, especially kalau makan makanan yang gas-producing macam beans or kale lah. Tapi kalau bunyi tu dengan perut sakit, bloating yang teruk, or diarrea, better check dengan doctor to rule out anything else la, just to be safe.
