Social Media

Anyone have good pointers on coping with social media and the copious amounts of pregnancies? Delete it? I have a friend that knows I've been trying for a while and she inboxed a bunch of people that they are expecting their third. I am happy for her but now the other 20 people in the chat are exploding the chat. Is it rude to leave these conversations? I want to be a good friend but it hurts. To be reminded over and over again that everyone is so fertile.
