I'm gonna be an aunt...again.

At lunch I got told I would be an aunt...again. Everyone else knew but me AND they all know we are trying too. Literally I think my face showed pure disbelief. Trying to get over the stab I felt because every month it's been BFN!! 😔 it just hurt, they aren't even married. And I know now days that doesn't mean much, but still. I don't know what to do. Anyone have any tips? How do I over come this? Tips I might try to get BFP?
