Bleeding for 11 days wtf

Taylor
So my period this month started off with spotting for 3 days before and now I'm spitting again after I thought my period was done. Grrrr. So frustrating. I've also been having a light period mid cycle. I think something could be really wrong. I have an appointment in a few weeks but I don't know if I should wait or go to the urgent care. Anyone been through this?
