Everyone else's good news!

I don't have anyone else to vent this to: I feel like a terrible friend. 
I've been home from work the last two days, bleeding and cramping. I have an Ob appt this afternoon but I pretty certain I've lost my baby. 
Yesterday a cousin announced her second (unplanned) pregnancy and a friend send me a video of the "Boy or Girl?" Announcement for her baby. Another friend sent a group message to all our college friends asking "Who's next?" 
This would have been the week I announced. I would have been next. My heart aches and I feel terrible but I'm so envious of these people. I don't even recognize myself. I used to be a good friend. Now I can't even congratulate a friend without breaking down. 
Thanks for listening. This is just awful.
