Melanie, I wish I had some advice for you regarding the spotting, but

if you haven't already, I would take this question right to the pink board too. I believe someone there would be able to speak from personal experience about the success after such a situation or whether their cycle was canceled and how that went.

I am so sorry you are experiencing this bleeding at all, but especially with your transfer being so close. Just know that either way, you WILL be transferring soon (either tomorrow or once the source of the spotting is figured out and/or it stops).

Wishing you the best in all of this!
