ttc help

Can a kidney stone prevent your period of coming? I have a officially missed my period. I have bodyaches, nausea, my breasts are sensitive and kinda sore. I was in the ER 2 nights ago for kidney stones and they did an urine and blood test which I was negative for pregnancy but the lady also told me to keep testing if my period does not show up. I got so discouraged but I still have hope for a positive result, and if not I'm just ready to start my period and try again.
