How to tell a possibly jealous friend?

I have 2 best friends, we all started TTC around the same time. Me and another have no health issues and both found out last month. The other friend has a line of fertility issues but she wants a baby more than anyone I've ever met. Us two preggos want to tell her but the question is how? I know she won't stay mad forever but I don't want to hurt her feelings. Advice?
