Why is it so awkward telling people you're pregnant?

For context I'm 29 years old and my and my husband's parents have been begging for grandkids for a while! So now that I'm pregnant with my first, why is it SO incredibly awkward telling our family that we're expecting? I just cringe at the thought of telling our parents and the rest of our family. I told my mom and then cried in the bathroom by myself because I was so mortified 😂 and I asked her to tell my dad and the rest of our family because I physically can't do it lol. They're all gonna know how the baby was conceived 😂😭😭😭 anyone else feel this way or just me???
