TTC #1, 1st cycle...symbolism of dove?!

So, my husband and I are trying for our first, and this is our first cycle trying...we are currently on the TTW (fingers crossed)...this dove will not leave our house...he just arrived 2 weeks ago and hangs out in this corner every night until the sun comes up....I have had people tell me that doves are a sign of motherhood (new baby), and I'm wondering if anyone else has had an experience like this, or heard of the wives tale?
