Hi I am so glad you reached out. Unfortunately, I couldn't find any information from past stories or forums about this topic from our members. I know it must be frustrating that the medical team won't let you skip a week of BCG while you have your period. Since that is the case, I would definitely ask them how you should prepare for that week during your treatment. I hope they can give you some good tips so that you know what to expect. Sending you strength. Jill (Team Member)
