Hi Babyhope...
I'm really sorry to hear that you think you've failed and are feeling hopeless. I believe everyone has their own personal journey of becoming pregnant. Your journey is via clomid, you won't be the first and definately won't be the last

My DH and I took 14-15 months to fall pg, the journey was stressful but its part of who we are as individuals and couples.
Keep your chin up and remember that you aren't failing in this whole baby making process, its just part of your journey into parenthood....
Good luck...
