Heart palpitations in early pregnancy?

Hi girls! So yesterday and today I’ve been having heart palpitations and a few sharp pains in my chest along with struggerling to get my breath (taking a deep long breath in) I went to my gp and they did an ecg and did my blood pressure and everything.. everything came back normal expect I may be suffering from anemia a little and anxiety.. is this normal? Has anyone else suffered with this? Worried me slightly xx
