unusal period

Roneka

for about nine days now ive been having light pink to bright red spotting not even enough to fill a panty liner and sometimes just when i wipe. my periods are always a normal flow so this kind of has me stumped. im hoping for pregnancy but i doubt it since i used the depo once back in march and havent been back since. just wanted to know if anybody experienced symptoms like this since starting then stopping the depo?
