Hello all!

I have looked all over and can't find this anywhere - I'm hoping you can help. There's a story in which Natasha wants to get pregnant and at first doesn't tell Clint, just sort of hopes it will happen by itself. Then she does tell him and the two of them work to get in the family way, which takes longer than they expect, although they do finally succeed. Anyone know where that is?! Many thanks!!

EDIT: Thank you, ashen_key! It's Only Human by anuna_81, which I HIGHLY recommmend reading, btw. :D
