hysteroscopy to remove scar tissue

Hey ladies! I had a hysteroscopy last Thursday (10 days ago) to remove scar tissue from my uterus in preparation for our frozen embryo transfer. I was told bleeding/spotting for up to a week was normal. It's been ten days and I still have some spotting. The nurse told me to give it until Monday. Which is fine, but I had my last birth control pill yesterday so should get my period soon. They don't seemed concerned with the bleeding but it's getting pretty frustrating. Anyone have a hysteroscopy and have bleeding for more than a week? I know many people have them just as a diagnostic tool, and have little to no bleeding. I'm hoping someone who has one where tissue has to be removed can help! Thanks in advance!
