Why is this happening?

Do you ever wonder why God, or the universe, is not allowing you to have a child? 
If it's purely science then that's one thing. But if it's God who is in control of our lives- then what is the purpose during this waiting period? 
I certainly struggle to see a reason why He wouldn't bless me with a child at this time. It seems like the perfect time for my husband & I.
We have been trying for 7 months and planning for well over a year. I never imagined it would take this long! I pray for a baby, we both do. Our families pressure us a lot to have one... I just wish I knew why this was happening. It's embarrassing to me because our families are waiting for a baby and it's "not working." I feel kind of hopeless sometimes about this... 
Can anyone relate at all to these feelings?
