Is feeling like your heart races normal?

Jennifer
So the other night I had a feeling where my chest started to hurt and then it felt like my heart started beating out of my chest and then like it skipped a beat and went back to normal. I ask my obgyn about that and she told me im dehydrated which seems weird to me. Then I've been fine for a couple nights but I started getting chest pain like 2 nights ago and feeling like my hearts beating a little to fast. And today I woke up with my heart racing chest pain and feeling out of breath. I know our hearts are suppose to beat more because they are pumping extra blood but has any of this happened to anyone else should I go to urgent care or hospital?
