Heart palpitations ?! Serious advice needed 😭

Sammy

I am 17 weeks pregnant and for the last 3 days every time I get up and walk (even just to the other room) I’m having extreme heart palpitations. When I’m at rest I’m completely fine it’s only when I start moving. Everyone around me keeps telling me I’m fine and not to worry but I’m terrified 😭 has this happened to anyone else?
