Should I be mad?

I am pregnant, 16 weeks pregnant. And my husband and I have only told immediate family and super close friends. We kind of just wanted to keep this pregnancy to ourselves. However for some reason my husbands ENTIRE extended family knows I’m pregnant. Which alright that’s fine if they know but we never got the chance to tell them and I’m pretty sure my mother in law told all of them which makes a little annoyed. Should I be? Or am I overreacting.
