As I understand it, a high FSH is an indicator of diminished ovarian reserve. They consider anything over 10 a high FSH. It basically means that you will start producing less eggs. So while someone with a normal FSH will likely produce 10-12 eggs for retrieval, someone with a high FSH may produce zero or just a few. As long as you produced the 2 eggs for your transfer, I would be very optimistic about your chances for a second round. The FSH limits your ability to get eggs (which is why AI takes a lifetime and failed for me)...but once you pass that hurdle things are much smoother sailing!
A high FSH SOMETIMES correlates with poorer egg quality, but that is less likely to be true if you are younger,
This gives a good overview of FSH:
