Announcing pregnancy

So my SO and I have been TTC for a year now and we're finally pregnant! But here's the thing I've been dying to announce it but my best friend who is also TTC just had a miscarriage and idk how to tell her. I don't want to be inconsiderate of her feeling because they've been trying for 4 years now and this is her 3rd miscarriage 😞. I'm really scared to tell her actually. But at the same time I'm so excited to announce it. Idk what to do! Please help!
