Hi Stick_insect (do you have those as pets? 

 ) Good that you haven't long to wait for the scan.
My fibroids were found incidentally - is that how you discovered yours?  What did you go to the GP for initially? 
I had a couple of periods with only 2 week gaps and some persistant spotting before and after, my GP sent me for an ultrasound to check for fibroids or polyps.  It was then I was told there were multiple fibroids pressing on my bladder etc.  Anyhow, I saw the gynaecologist this week and explained all my symptoms that I presumed were perimenopausal related but had begun to think it was maybe the fibroid.  In my case he suggested the symptoms were not fibroid related and that I had no symptoms that would warrant or need treatment.  I am very happy with that outcome and only have to pray the fibroids stay the same size and do not create symptoms.
I think it depends where the fibroids are, I believe mine are outside the womb, so therefore unlikely to be causing heavier bleeding and spotting.  It seems a bit crazy to me that I can have large fibroids but no severe symptoms.
I am making sure I excercise regularly, introduced green tea and probiotics - the aim of that is to keep my digestion tip top in the hope I eliminate any excess hormones as best I can. Basically to keep my metabolism going well if I can - it's a struggle I think as falling hormones make it slow down!!! Hence I also have a growing stomach, but that is hopefully the fibroids as well.
