I would definitely see another dr and maybe even another if that one doesn't help. It is possible that you are in pre-ovarian failure. But, there are many other things that can cause high FSH. There are other tests that can be run to see where the problem is. It could be a gland disorder causing the high #. I wouldn't give up just yet.
Looking at your varying levels.. I wouldn't panic. Get a second opinion from a RE. Good luck!
