I'm pregnant and I don't really know how to explain this sensation. It's not exactly a palpatation, it's like a flutter, that for one beat my heart beats really hard or maybe 2 really quick beat in 1, i feel it obviously in my chest and it goes through my throat (lasts a split second) kind of like the feeling of how your heart beats hard and fast after working out but it's just that feeling for one or 2 heart beats and I'm in a resting state! Will talk to my dr on Monday but just wandering if anyone else has had this problem before? It happens very occasionally!
