did I feel my baby move ?

Ma
Earlier I was playing with the Doppler since I have been feeling great, I wanted to make sure little one too. 
When I started to push where I usually find her heartbeat, to find it, i felt like a mass rolled in there tightly, like a flip. 
I was in shock, never felt that before, the feeling was very obvious.. 
i usually find her heartbeat one the right side and found it right after on the left.. 
im 13+5, im sure it's way too early but I was indeed lying down and pushing slightly on it. 
Could it be ? Did you ever feel that ?
