Pregnancy announcement

Did anyone have a hard time announcing your pregnancy to family? I'll be 23 and my SO will be 27 when the baby is born, and I already have terrible anxiety. I'm just so nervous to tell everyone when the time comes. My family had no clue I was TTC and they probably never would have expected me to right now. I'm not so much worried about telling my parents, my mom is really cool & my dad just doesn't say much but I'm scared that my grandparents will be disappointed. They have pretty much raised me and they do as much as they can for me. I'll be graduated with college before the baby gets here and my SO already has a job lined up. I just don't want to stress myself or the baby out about this. I know I shouldn't care what anyone thinks, my SO tells me it's my life and he'll be right next to me when we announce. I'm actually more comfortable telling his family lol. Did anyone go through anything similar? And how did it go for you?
