Hi Im 20 Yr Old Girl. Iv Been Eating Healthy

hi im 20 yr old girl. Iv been eating healthy and exercising regularly but the last few days i feel and look bloated. my stomach makes weird noises like just before you go for a poop, but i cant poop. i feel like cramps, like the stool is moving in my intestines. i think its probably constipation. pls confirm. also iv been eating a lot of apples - iv heard that apples aid in constipation...? pls advise :) thanks
