I pasted and copied this post from cjane 
 i still cry for couples i see experiencing infertility----even after 30 years---even after 6 children----its a deep pain that is hard to understand unless you have experienced it....I thought she said it wonderfully---so hear ya go:
Infertility is so much more than not having a baby in your arms.
That's  why you can't hand your crying baby to the infertile woman at church  and say things like, "Here, this will make you feel better. Aren't you  glad you don't have to put up with this?"
The woman experiencing infertility doesn't want 
your baby. Certainly, 
your baby is squishy and lovely (even when crying) and smells so nice, but that's not it. That's not even a consolation.
Nor  is saying to your infertile neighbor, "You should just adopt. If you  adopt I swear you'd get pregnant. It's happened to like, three of my  friends/relatives/coworkers."
Because, that's not it either. It's  not about achieving some ends to a means. It's not about belittling  adoption so you can achieve a pregnancy.
And adoption is not a scientific cure for infertility--and it's not an emotional cure either.
Infertility  is an all encompassing state of being. It has the force to completely  take over the core of a woman's belief about who she is and what she is  capable of. It's not about having a biological baby or an adopted baby  or a foster baby, it's about feeling whole even if no baby ever comes at  all.
It's about overcoming those days when you are called to  repentance (by well-meaning family members, or ladies at church) for  "lacking the faith to conceive" or for being selfish because "what is  taking you so long to have a baby?"
It's being able to love your  body even though it's not functioning in a fertile way. It's about  ignoring the statements like, "if you lost weight you'd get pregnant,"  or "the clock is ticking! you're getting too old," or "I don't know what  the problem is, my husband looks at me wrong and I'm pregnant!"
It's  the determination that no matter how family-friendly our culture is, or  how valuable we pronounce motherhood or how we like to say well-meaning  things like, "we're all mothers!" that the truth is we are all  daughters of a loving Heavenly Father. And that isolated characteristic  is mighty powerful in its own course. Anything else added to it is  cherry, but not necessary for our eternal self-esteem.
My own  battle with infertility ripped me apart. In those heavy years I felt  every emotion given to mankind to feel. Jealously like a furious ocean.  Anger, rage and self-directed disappointment. It wasn't just the  inability to conceive, it was the inability to believe in myself.
There was a lot of misunderstanding everywhere I went.
BUT. There is a belief structure that we preach in our church based on a scripture in the Book of Mormon it says:
Ether 12:27 And  if men come unto me I will show unto them their weakness. I give unto  men weakness that they may be humble; and my grace is sufficient for all  men that humble themselves before me; for if they humble themselves  before me, and have faith in me, then will I make weak things become  strong unto them. 
If we come unto Christ, He will make our weaknesses strengths.
I'm  not talking about being infertile for five years and then pregnant for  the next four (which, as it turns out has happened in my experience).   My weakness wasn't infertility which was washed away by strong  fertility.
My weakness was not seeing who I really was, with or  without a baby. I could only see myself as a person who wanted. I was  incomplete. And upon getting (miraculously) pregnant I didn't suddenly  understand, but somehow along the way I could see how the Lord took me  by my hand and showed me my strength:
I am a daughter of God, and  therefore entitled to intelligence, creativity, joy, inspiration and  beyond. These are my strengths.  
Real strengths.
That is  not to say there aren't residual wounds that came because of that inner  turmoil (I am still working on forgiving some of those "helpful" remarks  . . .)  I feel I'll never get over the entire experience completely.  And I suppose this is a post easier to write on the eve of having my  third child. But I remember saying to myself during those extremely  lonely years, "I want hope more than I want a baby." I didn't mean hope  that someday I'd conceive, I meant hope that someday it wouldn't be so  painful to be me.
This past week I was asked by Studio 5 to be a  guest on their Sensitivity Training segment. They asked me to speak  about how to talk to someone experiencing infertility. During the  interview I said a phrase I didn't get to really explain "there's light  at the end of the tunnel." It sounds so cliche and trite out of context.   I didn't mean conception.
I meant: the light at the end of the tunnel comes when the light inside of yourself illuminates who you 
really are, and what you're 
really capable of.
That's when infertility becomes less about having a baby in your arms and more about gratitude for having experienced it.
