Is it a bad idea to tell people you're trying?

My wife and I have just started trying. Into our second cycle and our fingers are crossed. Filling the diary and she got very high heart rate this evening (o-day) so she's taking that as a good sign so far.

Never had kids before but my parents live next door, very involved in our lives. I feel I want to tell them we're trying, like not announce we're pregnant but just to get their advice and guidance I think either me or my sibling was difficult to conceive for them, so just getting their perspectives might help.

Or is this something I absolutely should not do under any circumstances until we are pregnant 12 weeks?
