History of mitral heart valve prolapse...

Anyone else having heart palpitations/pounding heart/heart pain? I have a floppy heart valve, that pre-pregnancy occasional feels like it flip flopped. But that was the extent of it. Just once in a while. But now it’s so much worse. I went to the cardiologist and he said this is normal with pregnancy. I am getting a 24hr holter monitor and echocardiogram, but not for another month. It is making me super anxious since I can feel my heart all the time, and occasionally get heart pain. Just wondering if anyone else has gone through this, or had a similar experience?
