wow mel that is great that you finally have an answer ..

I too had the BT from DR S and that came back normal - i didn't proceed to have the biopsy done as i have always gotten an infection whenever a FS goes near me and Gavin didn't want to temp it!!! so he recommended that i do the steroids anyway and recently got a BFP which i sadly mc a few weeks later

Im now in the middle of deciding whether to have a D&C as i have only just finished spotting and have been having some pain and discharge.

i wish you all the best with the steroids - i didn't want to take them and am still weaning myself of them so GL
