During my first loss, an early one, I think I started bleeding around the 4-5 weeks mark. It was like a period so I thought it was complete. But I was still getting positive HPT's after that. I spotted a couple times here and there and this was awhile ago so I can't remember exactly, but I think it was about a month after the first (period) bleed I finally had a massive bleed. Like a heavy enough flow to almost be soaking a pad an hour for two hours. I almost went to the ER, but it slowed and so I waited it out. It was only after this bleed was over (a few days) that my HPT's finally went negative. I think my body just took awhile to release all of the tissue. If you are still getting positive HPT's and are not bleeding anymore, you may want to get checked out to make sure all of the tissue has passed. I am so sorry for your loss.
