i dont have any money right now. but i do need an answer as to why my period was a week early and only 3 days and super light. my periods are almost always on time and most definitely always heavy to where i have to wear a tampon and a pad at the same time just in case... sorry TMI. but they are always 7 days no less or more than that and so ive also been having hot flashes and slight cramping and god have i had headaches.. the thing that confuses me is i took a pregnancy test and it was negative but i still feel like something isnt normal with me can you explain what might be the cause if its not pregnancy?
