Depo and possible pregnancy

britbrat • I love being a mommy!!! Currently trying for twins! Gender dont matter!!
So i got on depo the end of aug, ive been on depo on and off since i was 15. Well now all of a sudden i guess im having a period, and never has this happened while on depo. I never had a period or bleed on depo. Its very very light, my normal cycle is messy and heavy. Its bright bright red. Has anyone experienced this? Has anyone gotten pregnant while on depo??
