Hi welcome to Health care magic forum.
you have got right lower pain, back pain
, and nausea
Your period is late by 10 days.
It appears that you have urinary tract infection
, or stone in the urinary tract
, or pelvic inflamatory disease, or poly cystic ovarian disease
. Delay in the period could be due to anemia
I advise you to consult a urologist
, for diagnosis and treatment.You may have to go for M.R.I.besides other routine tests for confirmation.
Wishing for a quick and complete recovery , and thanks for choosing H.C.M.F.
