Bleeding on BC

is this normal when being on BC?? I’ve been skipping my placebo pills for about 5 months now and over the past week, I started bleeding a little bit and suddenly a big gush of blood like this happened. ATM I just finished my BC pills for the month so technically I would take my placebo pills/ jump to the next pack. What do I do? Is this because I skipped my placebo pills for a few months??
