Heart flutters

Anyone else out there having more heart flutters and shortness of breath feeling? I’ve had heart flutters before but it seems to be happening a lot and for a longer period of time. I also am feeling some shortness of breath when it happens ( can’t tell if it’s because it makes me nervous or what). Anyways I was on an antibiotic my doctor had me stop it they thought it could be from that. But today and yesterday it’s sorta continued after being fine for a few days.
