20 day period 😫

Rachel
So I'm on the pill and instead of taking the sugar pills, I took the active pills to put off my period. I did a lot of research and have asked my doctor about that in the past. And now I'm all messed up. I've been bleeding for 20 days. Some days are really heavy and some days it's like nothing at all. I'm so annoyed and I don't know what's going on! 
Has anyone had this happen?! What should I do?!
