Unexplained?

Having such a rough day with things that have nothing to do with IF.

Also, I'm searching the interwebs looking for "unexplained inferitlity" support groups or forums but keep finding people that say they have "unexplained infertility" but then list: SA came back to show low count, or poor mobility; irregular cycles due to "x"; past the ideal age and have very few follicles. These to me are reasons for infertilty and therefore explained!! The doctors have found nothing with DH and I. WTF?! SA-good, Clomid challenge - good, follicles - abundance, hormones - normal, cycle - regular, tubes - clear. Yet still here we are 17 cycles in and nothing, not a single positive pregnancy test. This is so hard.
