Trying to stay positive....when all around me is negative..

My husband is making it hard for me to stay positive about having a baby. It's not that he doesn't want another child (he has an 11 yr old from previous), it's like he is wanting to happen right away. Today while putting up our Christmas tree (lol don't judge) he was like "some day we will have kids" and the tone wasn't an encouraging tone. And when we are out and find out a friend or someone we know is pregnant he says " everyone's pregnant but you." And then also working in postpartum doesn't help either. I have till Saturday before AF shows up so I am still keeping my fingers crossed.
