Al,
Yes. Those are normal side effects. Doesn't always happen right away and can take a couple days before you get them.
Here are a couple of places:
TICE (BCG manufacturer):
www.drugs.com/sfx/tice-bcg-side-effects.html
Dr. Lamm's site (see paragraph 3):
www.bcgoncology.com/treatment/bcgInst.html
I do recommend making a note of any symptoms/side effects you have, when they start, when they stop, etc. If you get a low fever, note that along with start and stop times (and what you took to combat it, e.g. Tylenol).
Bring those notes to the uro next time just to let them know. Dr. Lamm recommends reducing the dose if the side effects become too bothersome.
There is not evidence of reduced efficacy with lower doses.
If you get any of the big side effects, then you want to call your uro immediately. Those are spelled out in the pages linked above.
Best of luck for continued success with your BCG treatments!
