Hi Bri,
I have thought about this carefully and decided that I would go ahead and have a six month check because I would always be wondering otherwise.
I think I've made the mistake too often of trying to avoid checking on health issues in the past, thinking that if I put it out of my mind, it will go away.
I think that if you get a good result (which it probably will be), it will boost your confidence, if not, then you might as well know so you can start to deal with it.
Whatever you decide to do, good luck and try not to worry.
Take care.
Steve
