Colposcopy related bleeding

Hi ladies. I had a colposcopy done last Monday. It's now Thursday evening and I'm still bleeding pretty heavily. The first few days I wasn't bleeding too much as they had applied that substance that's supposed to help you heal. It came out after about 3 or 4 days and the bleeding seems to have gotten progressively worse. Sorry TMI, but I'm also producing a lot of blood clots that are coming out. Today they were pretty large so I'm starting to get worried. I've been soaking through a tampon in about 45min- hour. Anyone experience the same thing?
