Specific fic and 'ship request...

Hi guys, I'm looking for a Reid/Prentiss fic where I think they have a one night stand but then decide to not continue or something like that but then Emily finds out she's pregnant and they decide to have a relationship, that's all I can remember and I'm really really bad at remembering fic names and authors .
Also I'd love all your fic recs for the Reid/Prentiss 'ship please, all types welcome.
Thanks xx
