2nd pregnancy...nervous to share

So I'm pregnant with my second child. I am very early on but would like to tell my parents and siblings about it. My older sister has miscarried about 7 times at this point and did not handle it well when I told her about my first pregnancy. She is good now, she is my sons godmother and has a wonderful relationship with him, she just had a hard time with my pregnancy (I know it wasn't personal, it was a why me kind of thing)...anyway, I want to tell my parents next weekend but I can't do that without telling my sister as well and I'm worried about her reaction. I live out of town from the rest of my family so planned to do it in person. Should I call her and tell her ahead of time so she can have the reaction she needs in private? Or do I just tell her with the rest and hope for the best?

**no judgements against my sister please. I'm looking for helpful advice on how to tell her. And unless you've been through that much miscarriage and pain you do not have the right to make any negativecomments. **

I'm aware that I am entitled to feel excited about my pregnancy but I also know that something that is happy for one can be painful for another.

Thank you in advance and God bless
