Anja,
I also had my GCS with Dr Brassard, but on 30 April....as few weeks later.
I had major issues with fibrin on the last side of my vagina, and even in the vaginal canal....it took me 1.5 weeks of basically dedicated 24/7 air drying before the fibrin reduced. Now I have a rather large raw area which Dr Brassard says I'll take another couple of months to heal...all the while I need to keep dry and free from fibrin.
I'm not sure from your post what your schedule is like, but try doing some long term airing even though it may seen restrictive and boring.
Let me know how,it goes...please.
