My Hubby spilled the beans!

Sooo we agreed that we would wait until we're in our second trimester before telling everyone. I admit I did tell my parents, and a few siblings, but no one else. My Husband told my mother in law today, and I'm afraid she's gonna tell his whole family lol. Should I be upset or just chill. I'm just worried that if something goes wrong, I will feel bad that everyone knows. We have a five yr old, and prior to having him we experienced 2 mc. Maybe I'm overreacting we r currently 7 wks and 4 days. What do u guys think?
