Your FSH is a little elevated for 29, but it isn't that bad. The quality of your eggs coorelates with your age. You may not respond to fertility meds quite as good as someone else your age but your quality should be really good at 29.
I would not repeat the cycle day 3 bloodwork. There really is no added benefit to doing so. I would move on quickly and be aggressive with fertility treatments. I wasted half a year doing IUIs after finding out my FSH was 10.5 when I was 31.
I would make sure you have a good re that specializes in poor responders.
I had success on my second IVF. I was 32 and my FSH tested 18 at that time.
So 10.5 is definitely not something that should prevent you from having kids.
I would also be careful about reading too much on the Internet about high FSH. A lot of the information is outdated. They have relatively recently figured out that high FSH does not mean a patients egg quality is bad but just reflects response. So a lot of the articles are inaccurate and overly grim.
Sorry this is so choppy. I don't have access to a computer right now so I can't really elaborate.
