I can see my heart beat i think below my sternum. and to the left my left if i push slightly in makes a popping noise?

Get seen!: If you are having popping noises, especially if it like rubbing your hand over bubble wrap, this could be air under your skin: ER! It's really hard to say what is going on with the little history we have in the short amount of space. But do get checked out, consider a virtual consult on Healthtap Prime, where you can have a video consult with a doc. If not please go to an urgent care center.
