Major layoffs to come

I'm 7 weeks today and I've told a few friends and my boss's boss. (It's kind of like the movie office space here) We recently received notice that there will be major restructuring, not necessarily affecting me directly but there are a lot of people in my department acting strange and looking interview ready. My boss's boss has asked twice now if I told my direct boss yet and he knows that it's a little early to be telling everyone but he thinks she can "help me". I'm now feeling pressured to tell her today, oh and side note, she's crazy AF and has a huge mouth. I feel like I'm in a weird environment right now and I'm pissed that he wants me to tell her. I feel like they are up to something and he wants to talk to her about it me being pregnant and the possible layoffs or the fact they are possibly looking to leave themselves?? It's my information you know? It's not anyone's business until I decide to share it!! Weird times...
