Lower Back Hurt

I cannot remember if it is a monthly thing.. but i am jotting this down.. so that i would remember for next month.  But the man thinks that the lower back hurt.. has to do with the menses that is coming on its way.  I am not taking an pain killers for now.. but my fibroids had been a wee bit swollen today too.  So maybe ya.. the menses is coming perhaps.. and this is the symptom.
