I can feel my heartbeat when I place my hand on the left side of my chest. Is this normal? I can't feel my mom or sister's heart beat though so I am worried. Also, when I stay still I can see my hair move with each beat, if I place a post-it on my shirt, I can see that move with each beat as well. I am 27, F, overweight, not very active. I'm just afraid I have some sort of heart issue that's causing my heart to beat harder.
