AF or bleed from endo scratch?

So i started taking noretheristone on 25th May. On Tues this week I had an endometrial scratch (my AF was due on Wed this week). I was told by my clinic to stop noretheristone today ready for my baseline scan on 7th June. I got a little spotting after my endo scratch and this spotting turned brown yesterday (sorry tmi) which I assumed was old blood. My AF didn't come Wednesday due to the noretheristone however for about 6 days I have had period like cramping/pain and had thought that it was down to my AF wanting to come. Today I had blood when I wiped which was bright red and more than spotting and enough to wear a pad. I also have had lots of pain/cramping and period like symptoms but the bleeding and cramping have now calmed down. Does this sound like my AF or could it be blood/pain from the endo scratch? I'm confused.
