What Are The Early Signs And Symptoms Of Heart Attack?

Uhh...I had some questions about heart attacks

Im a 19 year old female.

For about two weeks Ive been pretty worried about a test.

I just finished the test though...And dont feel worried anymore.



Well I take that back...I DO feel worried.

Ive had a strange pain in my left side...Sometimes in the right side.(As of....Yesterday and all through the night on and off).The pain isnt aweful...Just irritating I guess.

My stomach is making lots of sounds,My knee feels like it has pressure in it(sometimes),my bottom jaw feels like it has pressure and my tooth hurts(Also sometimes).



My period did start earlier that it should have...So I assumed all was due to stress.

Could it still be stress?



I admit I havent been eating as well lately(junky things)..But now Im trying to drink more water again to get back into my health kick.



I dunno...I figured if it was a heart attack it would have hurt worse or Id already be in the hospital...
