Everyone is getting pregnant 😞

My sister was told no more kids and she is 7 months pregnant after ten years of trying. I just found out my other sister who was told was she was 16 she can't have kids is now 26 and found out she was pregnant yesterday. Both of my best friends are pregnant and my son is getting a half sister through his dad and stepmom in a week. Everyone around me is pregnant but me. I have to say I'm a little jealous more and more everytime someone calls me with news they are pregnant. Everyone keeps saying your next and they don't even know we are TTC but it's not happening yet. I should be happy for them and I am I just want my sweet angel too
