Bird watchers? Omen?

Anna
Hi. I'm from Canada and I found this little guy on my doorstep tonight. I'm 2 days late for af but got a bfn this morning. 
I think it might be a morning dove variety. I read that this is a sign of maternity as they, like mammals produce their own milk for their babies. 
What do you all think? 
Can someone identify this bird :)
