So I think I maybe pregnant (just waiting to retest)

Last time I just blurted out to my partner and he has said that with the next baby he would like for me to tell him in an unusual or funny way....

I'm leaning towards a treasure hunt 1. Where it all began 2. Where he proposed 3. Where we said I do 4. When 2 became 1.

But I'm stuck on the hints for place 1 and 2

(3 is going to be a baby groot toy as that is the nickname we have picked out for future bump and 4 is going to be me and my son and the possitive test)

Does anyone have any other fun or cool ideas?
