I didn't change FS but got a second opinion from another FS. I was really upfront with FS that I was going to get another opinion...that it wasn't personal but for my 'mental health'...just needed to know there wasn't something else out there that we should be doing. When I went to 2nd FS I told him straight up why I was there...he spent over an hour going through all our results from previous cycles and in the end offered the same opinion re where to go next. We decided to stay with our original clinic as it was closer to home but I would have changed if I believed there was something better or differrent on offer. Just remember this is about YOU! You are paying them for a service and if your needs aren't being met...tell them...move on...do whatever you need to do. Looking back in five years 'wondering' will be worse than the short term 'pain' of being upfront. Good luck
