When will I feel my baby move/flutter

I'm currently 15 weeks... I'm a little chubbier and was always chubby in the stomach even before i got pregnant and I'm afraid that since I didn't have a flat stomach, I won't feel the baby move as early and I won't get a good bump... So far when I suck in my tummy, it looks like I have a little bump but it's squishy AND hard
