Bleeding for 34 days

Hi, I had a baby a year ago and didn’t have a period after having him. I am still currently breastfeeding and 34 days ago I started spotting. I spotted for roughly 2 weeks until it turned into a full flow. I called my dr and he put me on progesterone only bc which haven’t helped at all. I only have 3 pills left and have not stopped bleeding yet. It’s been days where the flow isn’t as heavy or may have seemed like it was going to stop but it never does. I do however have pcos so idk if that may be a factor, but I also have two other children and this has never happened to be before. Has anyone gone through the same and may have answers?
