Heartbeat feels like I had too much caffeine

Grace
Does anyone else feel this? Everyday around late morning l, early afternoon, I feel like I drank too much caffeine and my heart is pumping and  I am out of breath.
I got an EKG and did a heart monitor and everything is fine and I heard heart rate increases when you are pregnant since you are pumping more blood...
Just wanted to see if I was not the only one...
