At the start of my pg I didn't - I kind of felt embarrassed, I guess. But as I slowly started to mention it, generally when someone else said they're having trouble, or they've been trying for a while, I found it easier and easier to tell people. Now I feel that it's important to mention it, because it shouldn't be a taboo subject, and so I feel like it's almost a responsibility to not shy away from mentioning if it's appropriate. I usually say now, 'Well, we needed a bit of help to get this one, so... (we're not sure when the next one will be, or so I can recommend a good FS if you're interested, or so you can feel comfortable telling me more of your story, or whatever.)
