I've always had anxiety. And I've always panic with the feeling of my hearth beat. If I feel it while laying down I turn the other way, or never lay down in someone's chest because the beat of theirs will make me nervous too. I read that while pregnant our heartbeat will beat a lot faster. But today I started feeling sick so I came to lay down and felt my heat beat very fast. I have like an uncomfortable paid in my heart or so I think. Has this happened to you?
