I don't know I'll tell you when it happens LOL! Seriously though, I don't think there is a rule as such, I think everyone is different some are lucky enough to just look at each other and others have to go the long haul like myself, or you have those in between. I really hope your TTC journey is a short one and you can be announcing from the roof tops in no time! Goodluck!
