Heart racing & light headed

Tiphineigh

I have moments where even the smallest amount of physical activity takes a toll on me. Sometimes I’m completely fine and can go on a walk with my husband and everything is fine. However often like today, I went to target and had to leave before I was done shopping because my heart was racing out of my chest. I had to go sit in the fitting rooms to try and settle myself down. Is this normal with any of you? Very abnormal heart racing which makes me a little light headed and start to sweat? I plan to bring this up with my doctor at my next appointment this week but so far all of my symptoms I’ve had they say is totally normal and nothing to worry about. Just need some other momma perspective :) I’m 20 weeks.
