My struggles and introduction

Just introducing myself... I'm 38.  My husband and I have been TTC for 4 years (technically 3, he was deployed for 1 of those years).  We've been through 1 miscarriage, 3 IUI's, 2 fresh cycle IVF's, and one frozen IVF cycle. We have 1 frozen embryo left to try next month. If that fails too, we're planning to start over with a third egg retrieval and fresh IVF. Our hopes are thinning, almost as much as our bank account. We don't want to give up, but I feel like we're getting close to the point where moving into acceptance will be necessary.
