I just blew up on my mother in law and please tell me I’m not wrong.

She calls to tell me my sister in law is pregnant and how something is wrong and she might lose the baby.

I asked if said sister in law knows she’s announcing this to everyone and she said no and kept going about how awful this is going to be and how they can’t deal with it again and she would just be so torn up (talking about herself and no regards to her own daughters feelings). This same sister in law already had a stillborn at 39 weeks. So I’m sure this is devastating to her and yet here is her mother all concerned about herself and telling everyone her daughters business and it really pissed me off. I told her quit running her mouth and she would tell the family when she was ready and when she knew any actual information.
