Welcome lillibird,
BCG seems to have been off and on for several years on availibility. While 6 weeks may not be a big problem, you do want to get going in attacking things, since you have been fighting this since 2016. I would phone around other URO offices, teaching hospitals or major centers that treat bladder cancer and see if you can get some. In the past year,
a newer agent, Gemcitabine and Docetaxel have been used by several posters and it does appear to be a good sub for BCG. You may also want to ask your URO about this. I have linked one of the discussions on the board a bout a year ago:
Gemcitabine/Docetaxel monthly treatment - Bladder Cancer Support Forum
