How to announce you're pregnant to a friend who is TTC?

So, a friend and I have been discussing our TTC struggles over the past year and I never thought about how hard it would be to tell her when I actually get pregnant... I'm only 5 weeks along and have had one mc and one chemical pregnancy so I'm not exactly ready to tell anyone yet, but I'm not sure how I'm ever going to tell her when I am ready. I hate to be the reason for another heartbreak for her 😔 I know many of us struggle with seeing this happening to others and not to us... I know she will be happy for us, but I want to let her down gently!
