My best friend for the past 8 years is ttc and just got disappointed by AF. I just got my bfp I want to tell her because I tell her everything and I’m excited but I don’t want to hurt her. What should I do?

If I wait until she could gets hers (hopefully this up coming month) I would feel like I’m stealing her thunder. But if I wait to tell her until I’m ready to tell everyone she will be hurt because I didn’t tell her before.

How can I avoid hurting her? HELP
