Heart palpitations?

I’m 19 weeks and I started experiencing heart palpitations recently. It’s not that my heart rate is high or my heart is pounding, it feels like my heart stops and then beats a few times at once, for lack of a better way to describe it.

I’m not anxious (I’ve got a lot of past experience with anxiety) and it’s happening when I’m relaxed and not exerting myself physically. Is anyone else experiencing this?

I went to the doctor today for a routine appointment and she said my heart sounded fine, blood pressure was great and only to worry if I passed out or had any other symptoms, or a heart rate at 120 while resting. It’s super scary and uncomfortable though!
