Needing so advice when it comes to announcing

So I’m currently pregnant with my second. To convince my first it took a long time and we had tried medication to help my fertility since I have pcos. We did it naturally with my second and I’ve had two ectopic and a miscarriage between my first and now which no family knows. but am struggling on how to tell my sister who is still struggling with infertility. She was upset when I announced the first time but she was happy for me because she knew I was struggling with infertility myself. I announced last time before Christmas because family was in town and I custom made wine labels and gave them two both my sisters. The one with infertility gave it back and said hold on to it for when I can drink it with her. We never drank it and it’s just sitting at my house. I did a bigger gestures with announcing because it was my first and I didn’t know if it would ever happen for me. But now with my second I’m just going to announce normal with no gift other than for my parents who live far from me. So my question is what is the best way to tell my sister that is struggling with infertility still or any advice on how to tell her?

Thank you in advance 🙏🏼
