33 weeks and 1day pregnant

Hello. im 33weeks and 1day pregnant. Is it normal na sumakit balakang at puson at the same time. minsan naninigas rin tiyan ko and also may time na i having a diarrhea. wala rin ako gana kumain minsan. feel ko nag babawas katawan ko ng timbang. i just want to know if someone experiencing this also. #advicepls #pleasehelp
