Possible kidney Stone

Hey , im new here , i had a kidney stone nearly 3 years ago in my right kidney . i do beleive ive another one , there is a slight trace of blood in my urine . no infection tho !! slight pain in right kidney but bareable. I seem to have more pain that feels like it’s in my tummy at the side . feel sick most of the time . doctor done bloods but they have come back normal , has anyone else had a kidney stone with normal blood works? the 1st stone I had was so bad , this time it’s not so painful im worried it’s something else :drooling_face:
