Yes, that's a bit weird. I've been told my fsh is good at 8.9 (taking into account my age--which was 39 at the time). 14.5 would be elevated but 4.5 is great
4.5 is a fantastic level - I don't know what your RE is on about!!
Are you sure you got the level right? Anything below 10 is considered excellent FSH. FSH at 4.5 means you have teenager's eggs!!
