FTM Question

Hi all! So this may sound really dumb, but I’m a first time Mom so I’m curious! When all is calm and you’re just laying down, is it possible to feel baby’s heartbeat through your stomach? My belly pulses right below my belly button and to the right, where baby seems to be. Also, I feel him moving in there when I’m relaxing with my hand on my stomach, light flutters and twitches. I know that’s possible, I’m just really curious about feeling the heartbeats! Thanks! I’m 15w2d!
