Bulk email

Mail from unknown addresses automatically goes to my bulk mail, and I am expecting an important email from someone not in my address book. I accidentally deleted all of my bulk mail without scanning it first, and I need to check it and see if that email was in there. It didn’t go to my trash, and I have searched my mail for it with the search button, and it’s not coming up. Does that mean that I can’t get it because it was bulk, or have I just not recieved it yet?
I did not hit Empty next to the Bulk folder. I opened the bulk folder, selected all of the email and hit delete. it should still be in the trash, right?
