Dear Kaye,
Welcome to the group, it has been a pleasure getting to know you from your posts. It seems like you are on a very good transfusion schedule - 45 days is a great interval between transfusions. It is also nice to know that you are studying and doing well. It makes my day to see a young person like yourself looking after your health and asking questions that will allow you to take good care of yourself.
I hope that you keeping your iron levels low and that your are taking supplements to protect yourself from iron damage.
Best of luck,
Sharmin
