We have set a date for our church wedding!

Yesterday we decided to set a date after over a year of ttc we've realized were not going to have family any time soon not because we giving up its just to heart breaking to go thru a negative test every month...at the beginning when we started ttc we talked about this if we didn't get preggo after 15 months that we would get married at the same church I grew up which is an 1hr. Away but that's the only church I would get married at...I know this should make the happiest women in the world but not really....I can't get over the idea that I can't get pregnant...WHY?!
