spotting on predicted period day!!!

Kelly

Okay so this app is always a couple days off and I just got OFF birth control in January. so this month I was supposed to start yesterday and I had cramps and kinda sore boobs but I only spotted a tiny bit. then all night I cramped and very light spotting again! me and my husband aren't trying but don't care if we get pregnant. I'm just wondering overall if any of you spot before your periods?
