Rich360,
Blood clots are not unexpected after BCG treatment. For many of us our reaction to BCG increases with additional treatments; others report no response increase. Bits of tissue, urothelium , urinary casts and blood clots can all show up in urine - which we tend to pay more attention to after BCG treatment.
It is likely that 'things that look like blood clots" are blood clots. They can provide a unique sensation as the exit the body.
Large clots, in large quantity can block urine flow, and require prompt treatment. Talk to your doc about when to call the office if you become unable to urinate. Also ask about liquid consumption suggestions after BCG treatment.
Best,
Jack
