my "period" is two days early which NEVER EVER EVER happens. & it's so light which also never happens. my period always comes in the morning and it came at night.. I have barely any back pain which is also bull crap because I usually have to pretty much sedate myself for the pain to stop & I have the weirdest pain in my abdomen.. also boobs have been hurting for a week and still hurt I also never get tender boobs with a period.. what is going on?! any suggestions?
