Friend pregnant but not me

I don't know what to do this weekend I found out my sister in law is pregnant with her 3rd and found out that one of my friends is pregnant as well. I took my sister in law telling me pretty ok at least in front of her I was ok. But when my friend told me I ran out of the house and cried in my car for about 20 minutes and my hubby came out of the house and we left. I texted her that I was sorry for acting the way I did but she was mad obviously. Idk what to do everyone says it I'll come but I'm so hurt. And my hubby thinks I should be happy for them but it's so hard..
