Yea its not been easy especially for her but I am always telling her to have faith it's going happen and that plenty people have gone through the same and have had kids. Also like you said there is a lot of options now medically to  help. Which we will go that route later this year if nothing happens by then.  Its something becoming very common lately because a lot of people held off having kids while young. 

 It's a bummer that people aren't trying younger.  Obviously a big topic, but as someone who has been trying to get his own faith back fwiw, I'll keep you and yours in my attempted prayers.
