Heart keeps jumping a beat?

Jordan • 26 with 2 boys, our 3rd beautiful creation is due 16th of September 2019❤️❤️❤️

Since I before I found out I was pregnant my heart keeps beating irregularly quite often like it’s having a little random dance. I won’t be seeing anyone for another 2 weeks. I’m 7 weeks 5 days. Has anyone experienced this? Should I see a doctor? I’m a little nervous.
