I think my mom gave away our announcement

Jen • I make boys! Or I should say my husband does...we have our third little guy on the way. Due November 6th 2016!
My twin sister and I are both pregnant! We're literally a week apart and it's pretty exciting. We've told our immediate family but waiting to tell the extended for my sons birthday party next weekend. My sister and mom were over yesterday and she asked her if she's told and she smiled. My feelings are kinda hurt, for super silly reasons, but still hurt. Do I still do the announcement I've been planning or just casually say it?
