I was told that "you are only as good as your worst number." That said, a low FSH month increases your odds. Good luck! On a side note, I have since adopted, and it seems like it was all meant to be. I am thankful for my "bad eggs" now!" At the time, though, it was SO hard living by these numbers and what they meant---hang in there!

I tested 21 once and then 8... I also had 2 unassisted pregnancies that resulted in two births after that first test

Yes, it varies. A better indicator of your response to fertility tx, as well as egg reserve, is to test your AMH, which is a blood test that can be performed on any day of your cycle.

What have your FSH levels been like?

It varies by month but not by a lot. If you have 8 this month it could be 10 next month, but not 25.

I get tested every month since starting seeing an RE, but it's always different.
Isn't it supposed rise a little every month? Am I wrong?
