Heart beating fast?

Brittany

I’m 28 weeks now and for the past couple weeks I’ll have random episodes throughout the day where my heart feels like it’s beating super hard/fast. I thought nothing of it at first because heart palpitations are normal during pregnancy. But one time it got to the point where I almost fainted. I measured up to 119 bpm at one point. I emailed my OB twice about it but both times she told me it was normal. It’ll come at random times (a lot of times while just sitting) and will last maybe 5-10 mins, about 3x a day.

Has anyone else been experiencing this?
