Racing heart?

Mama to Oscar • Mama to my beautiful boy 👶🏻

I am currently around 6dpo. I have noticed today that my heart is racing on and off. I can feel it in my neck and hear it in my ears. (It’s racing to the point my boob is wiggling to the beat). My breathing is fine and there is no pain. (It’s not covid either FYI). Is this a very early sign? When does the amount of blood in your system increase? I’m just curious if anyone else had this?
