I saw my surgical team this afternoon to discuss how we will proceed now both my implants have turned. 
As a quick update; I had the anatomical implants which are tear drop shaped, they have both turned so that the fullest parts are now facing toward the centre of my chest instead of downwards as they should be. 
Because they have moved bits are sitting in the wrong place and pulling parts that shouldn't be pulled and this is getting a bit uncomfortable (not painful but a bit achy).

We came to a decision that the best thing to do will be to surgically remove my current implants and replace them with the round implants. That way if they turn again it wont make any difference to how they look.
This surgery will be done under general anaesthetic but it will be scheduled as a day case meaning I wont have to stay in the hospital over night and I shouldn't need any drains.
As I have had my nipple reconstruction over the original incision the surgeon will make a new incision in the fold under my breast. 

I have an appointment at the end of June to measure for implant size and the surgery will be done in September. 
Obviously it is a little disappointing that I have to undergo a second surgery but it will be much easier than the original mastectomy. Hopefully come September this will all be finished with!
