Depo gon WRONG

Long story super short , I was given a depo birth control shot after I had my baby ( may 27) days after I was bleeding which is normal I just had my baby . 6 weeks forward I'm still bleeding? With my twins ( whom I had 7 hrs ago) I don't remember bleeding for that long. I went to my doc she said it's because your lining of the uterus will clear and stop bleeding. ( okay ? ) so now AUG 17 I'm ASSUMING ITS MY FIRST PERIOD and now two weeks later I'm still bleeding?!!!! Is this cause of the depo? Or is my period just two weeks long now ? ( usually it's normal 5 -6 days. I'm so mad because I never asked for this shot and I'm dealing with this not knowing is this a period lasting this long or just because of the depo? I'm never NEVER GETTING. IT AGAJN . I jus wanna stop bleeding ! It's heavy and light with no cramping ahhhh
