My Heart?????????????????????????????????????

Question:

My Heart????????????????????...

Im 13 and I dont have any heart problems in my family tree but for some reason my heart beats hard even when I haveint done anything. I cant feel it but I can fell it when I touch my chest. It doesnt skip or give extra beats but its just making me nervous.
P.S it doesnt hurt either. And there is no other symptoms while it happens, not short of breath or anything like that. Could this also have anything to do with puberty or being over weight?
