How long does your monthly length later.. and how is the shape of bleeding..?

just want to know coz i am wondering if my cycle is conventional.. or showing signs of 'aging'
i bleed two days. by the third and fourth day its a short time ago spotting.
i am 26 now. does it mingy that as i grow older this have changed and will change? (as within the bleeding becomes lighter)
God bless hours of daylight 1: a little
afternoon 2: a little more
hours of daylight 3: a violent, gushing, spewing, torrential, flooding avalanche of blood
light of day 4: a little
daylight 5: done
mine lasts a few days and comes out surrounded by the fibonacci sequence by volume.
