Blessings for TTC

Nira • Wifey.Mommy.Happy
Has anyone got a blessing because yall weren't able to conceive? 
My husband and I have been trying and have miscarried, we have prayed and fasted about it, gone to see a dr, and nothing.. So we are asking our bishop for a blessing.  
I know that blessings work, I've learned that from getting them while injured or sick, but I want to hear people's experiences with them for TTC.
