i was a few days late n thought i might of been pregnant but then i had a 3 day heavy period on 10/13/10 but then around the 25th i noticed a light red kinda pink when i wiped then a couple days later i began to bleed again like a full period for about 4 days...but since there still is this like light red/pink when i wipe there is like little spots on my liners as if im spotting lightly then today when i worked out when i went to the bathroom it was a darker red when i wiped what could this be?
