Heart palpitations and racing heart feeling

I’m in my second trimester.

A lot of the time it feels like my heart is racing and beating really really fast. It makes me uncomfortable it feels so fast.

But when I look at my Fitbit, it’s pretty normal and not racing at all (75-85 resting)

I know palpitations can be normal in pregnancy, and have had an ekg and everything looks good. But it just feels like my heart is racing when it’s not.

Is this normal?
