How to deal with baby fever.

So I’m struggling really bad with baby fever. My sister just had a baby, one of my coworkers is pregnant and so many people on my facebook are making announcements. I know my husband isn’t ready yet and now isn’t the best time for me to get pregnant, but i’ve been really depressed every time i think about how much i want a baby. Does anyone have any good suggestions on how to deal with this? And i’m sorry this is such a long post...i just have no one i can talk to about this.
