Im 33 yrs & for a year now my period became 30 days &lasts for 7 days. but for the past 4 months since starting gym it is now 28 days &lasts 7 days &also before it starts by 3 days or sth there is light spotting even with no sexual activity as well?

Period variation ?'s: With fairly regular periods, spotting can occur as estrogen levels drop rapidly just prior to onset of menstruation. At age 33, there is higher estrogen produced by the ovaries, and as production decreases, the thicker lining of the uterus will partially degenerate allowing slight bleeding to occur. To alleviate this , your gyn may recommend low dose oral bcps.
