Advice Needed

Sarah
Hey ladies! I need some advice. I'm about 7 weeks pregnant and have chosen to wait to announce my pregnancy. However... My sister in law and very dear friend lost her baby in April. I do not want to upset her when I tell her I'm pregnant. She is the sweetest person I know and delivers babies daily so it's been hard enough on her. How can I tell her I'm pregnant without upsetting her?
