has anyone here experienced heart palpitation while pregnant? i’m 17 weeks pregnant with my second and never experienced this with my first. normally it’s just a few minutes and goes away but it randomly started while i was laying down and my chest is hurting and it’s making it hard to breathe. i’ve had this feeling in my throat all day where it feels like a balloon is stuck in my throat, or like i struggled to swallow a piece of gum or something. should i be concerned?! help 😩
