HELP! Okay so. .. I visited my Uncle and his fam last Summer. While there I tried talking to my Aunt about TTC and miscarriages since I'd known she'd had several losses too. Her total attitude changed and she shut me down. Instead of a bonding experience I felt like we got further apart. They have 2 adopted children that are older than my 9yo so I didn't think she'd react that way. Now I'm going to see them later this month and I'm 7w pregnant. I honestly don't know how to act around her. I'm so super excited but don't want to hurt her. What should I do?!
