Announcement photo before pregnant?!

So my husband and I have always talked about how when we got pregnant we wanted our announcement photo to be our bassinet in a sunflower field with a sign or something saying “Coming Soon Baby (insert last name here). The sunflower field by our house is looking its best right now and with the outside temp at 106 degrees, they aren’t going to last long. I am not currently pregnant but we’ve known it’s what we want for a long time. Is it crazy to take the photo and save it on the camera for later?! We would only use it up until November, as a sunflower announcement in December would be odd. Are we crazy or does it make sense? If we don’t do it now and get pregnant in a month or 3, I would be pretty disappointed. (My great grandmother and Mom always had a thing about sunflowers.)
