Hi Amy13! So sorry to hear your story, it is such a tough journey. I am also having treatment at the Spire/BCRM. Just waiting for my womb to recover from a m/c and 2xoperations to remove the pregnancy and will then be starting again, probably around April.
I am roughly the same age as you (turn 36 in May) and have low ovarian reserve. I was lucky enough to get pregnant last year but it didn't work out unfortunately as our baby had a trisomy. It is so hard when all of your friends are on their second or third babies and you feel stuck at square 1. I've found it to be a very isolating experience. However, I have found a huge level of support from threads on FF and have even made some good friends as a result.
There is a good thread for people currently undergoing treatment in Bristol - http://www.fertilityfriends.co.uk/forum/index.php?topic=357410.new#new
Although its titled BCRM current cyclers it includes people having treatment at the Spire/BCRM. It's fairly quiet at the moment but I know there are a few people going through/about to go through treatment.
Best of luck with your cycle xx
