How to make the next treatment decision?

libellula28

I am currently 41 with secondary infertility.  I have had all of the testing done, and the only issue I have is a lower AMH.  The first time I was tested it was .29, so I took DHEA, Vitamin D, and Ubiqinol and the number raised to .628, which is promising.  However, I am AMA, and really feeling the pressure.  We have tried to clomid cycles, which didn't end in a BFP.  I have talked with my doctor and discussed IUI and IVF.  He said IUI will only increase my chances of pregnancy to 5-6% a month, whereas IVF will increase my chances (of a live birth) to around 50% at 4 treatments.  My partner and I are not a rich couple, and a 4 round cycle is around $30,000.  While I see the benefit of IVF, I don't know how to make this choice.  I think my biggest fear is trying IVF and being let down.  We've been trying for almost a year with no success and it is emotionally the hardest thing I've ever been through.  I don't really have anyone I can talk with, so I am curious how all of you all made the decision as to which treatment option to try. Thank you all SO much!!!
