Girls ONLY! guys skip over this press plz?

i have absoloutly no cramps, or backache related to my periods. everynow and later i'd get for a moment pain but resembling a little pressure. Don't procure me wrong i still have the mood swing and all-just not the discomfort. Is this normal, honest, bad, should i see my doctor? give an account me plz.. very worried This could be everyday, eveyone's different, I know some girls who don't cramp, an some who can't get out of bed. so everyone's different. (feel blessed).
