How do people do this for years?

I don't have the results of my prog. test yet, but I am calling for them in the AM. Today when I got home from work, I had some spotting. *Insert tears here*. I'm not sure if I am crying because it didn't work the 1st time or because I know what that means for the next cycle---it's my last one until April 2014. 6 months away. Because I know my LPD is going to get worse the older I get, that 6 months seems like an eternity.

I feel defective and broke. How did I go from 4 pregnancies between 19 and 22, and now I'm only 7 years older and struggling? I'm frustrated, sad and just annoyed. I'm one of those people who likes to things 'right' the first time. When I can't get it 'right', I tend to give up. That's what I feel like doing right now..because I can't keep getting my hopes up. Of course when the time comes and it's time to take Clomid again, I'll do it--but right now, I just want to quit.
