I had my period and since then I have stomach pain and kidney pain. Is this normal?

During menstruation it is normal to have pain in the lower abdomen and lower back. Are your periods completely over? If not, acetaminophen (Tylenol) may help (avoid Advil if you are allergic to naproxen).

These symptoms are also reminiscent of a urinary tract or kidney infection. Such infections may be accompanied by a burning sensation when urinating or the feeling of always having to urinate. If this continues and your period has been over for several days, you should seek medical attention
