question regarding exposure techniques

According to this book I am reading now, i wrote down my list of exposure triggers, one of is visiting dr (related to the fear of hearing bad news). So it may be a good chance of an exposure, my tomorrow visit to gyn.

But on the other hand, book says that i should avoid anxiety-reducing strategies which includes obtaining reassurance.
It is actually my reason of going to dr, getting reassured.

So should i just skip this exposure chance? Or should i just ask dr to make control without telling my worries and suspected symptoms. I dont know if i survive this stressy thing without reassurance really.

Maybe it is too early for me to test a high hierarchy exposure, since i am shaking like a leaf and so nervous.

Thank you S.C. :)
I will leave the exposure direction to my future therapist. Tomorrow will be just a control that i need to do, since i had it last 2009 -.-

My ache/discomfort symptoms are mostly gone, except for bloating which is very known to me.
