2 week wait sucks :S implantation bleeding

Ok I have a long story :S but let me bring it down to what I need to know :S I'm currently in my 2WW and AF is due 11/2 :S but I'm hoping she dosent show up :) I tried my first cycle of Clomid earlier this month and have been praying it works ;) and have heard mixed reviews on it working or not :S so my question is this, how heavy or light should implantation bleeding be and how soon should you experience it?  I'm in tune with my body now :) and this morning when I used the bathroom I wiped and noticed very light spotting, and have light cramps, but the cramps fill different this time.  Not like menstrual cramps it's funny :) so I just wanted now if it is to soon to be experiencing anything such as implantation cause AF is do in 2 days :)
