Phew, I'm home, finally! Traffic was horrendous and we ended up just over half an hour late to our appointment 
Righty is still hovering somewhere over the top of my womble, and now has 6 decent sized follicles (about 15 x 18, I can't remember all of the measurements they called out) and a couple of smaller ones.
Lefty has actually grown three follicles! There are also a couple of smaller ones there too.
Womble lining is nice and plump, and the polyp didn't even get a mention today, until I asked if it was causing a problem and they said no. The fibroid's still being a bugger though.
They want me back for another scan on Sunday morning (I didn't even know they did weekend scans for NHS patients!) with the expectation of EC on either Tuesday, Wednesday or Thursday next week.
Thanks for all your brooking, once again it proves that it works!
