Need advice

My husband and I are currently TTC and I've been debating on how to tell one of my older sisters that I'm pregnant (when it happens). She has struggled for years with fertility issues and gave up trying about a year ago after a failed <a href="https://glowing.com/glow-fertility-program">IVF</a> attempt. I know she will be happy for me, but I know it will also be hard for her too. I originally wanted to tell my whole family at the same time. Now I'm wondering if that would be rude and if I should tell her separately first and then announce to the rest of the family.
