Good luck, I hope your doctor realizes this is just passing thought.

In the future, if your doctor wants to talk to you it might be better to just come out with it right away and stress that you will contract for safety, you just wanted to make him/her aware of your thoughts. If you time it and phrase it right, they should know you're just being safe. Eventually you'll build up enough trust that they believe you outright with less convincing - but then you really need to take responsibility and tell them if you're not safe.
