Hope I'm not offending anyone by posting on here since I have a LO. I was actually looking for the DOR check-in when I saw your post. I had similar stats to you: FSH was 13.3 (but was probably actually higher as it was suppressed by high estrogen), AMH = 0.54 and was 100% OOP. I also had a really short luteal phase. [And I still do - my first post-partum LP was 3 days!] My RE gave me a less than 10 percent chance of conceiving WITH art, but yet I just had a little one. The only issue we did not have was that you do is that we didn't have any male factor issues.
Here is my thought - Have you tried any of the less expensive methods like just doing Clomid or Femara, or Clomid or Femara plus an IUI? I think clomid is like $25 or something. And even clomid or femara plus an IUI is alot less than injectables...I have a friend who has done clomid/iui six times and each time I think it costs her about $300. Mine was about $600 but I had an ultrasound that was IMO unnecessary and I think that was half the cost. The reason my DH and I went this route was because it was so cheap...you can do a whole lot of rounds of clomid or femara for the price of doing one round of IVF. You can even do alot of clomid/iui for the price of one round of IVF. IMO, everytime one of us DOR ladies does a round of ART, it is just like spinning a roulette wheel.
Another thing you might look into is some of the alternative treatments that are cheap for DOR that is supposed to improve egg quality/quantity like taking CoQ10 or doing chinese medicine. If that didn't work, though, I think that IVF would be a good option. It will take out the male factor issues for sure. If you go over to the Success after IF board, there are alot of women with stats alot worse than yours who have gotten pregnant with their own eggs. And your AFC count was 6, right? That is not a terrible count at all. I would think that IVF with your own eggs could be a good potential option.
