Me venting...No baby yet again...

My husband and I have been ttc for quite a while now. This month I was so sure and so confident. Only to awake this morning and see that evil red stain... I thought this disappointment would get easier, but we've begin coming to terms that there's a real possibility it just may never happen. It's so discouraging and disheartening. I just don't know how much longer we can go through this.
