Bleeding for months ffs

Anyone been on the depo and basically bleed the whole way through, I missed d my first period after I got it, cool cool. But got the one after that - and basically haven't stopped bleeding since! Its not a period bleed all the time though if that makes sence - like I still get my normal period and have constant light bleeding in between. Wtaf, I work away and just haven't had time to get to the doctors, I'm home next week so I will go then but seriously!
