Some people do some people don't.

well, im very very dizzy, i feel like im going to puke at random times of the day, i have slight cramping and my boobs are a little bit sore...this is very rare for me because before i start my period i never feel it coming, it just happens. i took a test a few days ago and it said negative, but my period isnt due till next week. so right now i have no clue what to think....

i started my my period a week early. or what i thought was my period. but it started out just like implantational bleeding. its weird i dont bleed at all but spot but when i go to the bath room a clot of blood comes out. like pinkish reddish. i have no cramping. just headaches nausea and sore boobs.

is cramping normal??
