Rant.. Sorry ladies

B❤
My mom is beyond excited for first grandchild. I'm obviously not far along, and she's trying to plan out baby shower stuff. Making a list of names. I told her to stop. You don't know what could happen right now, haven't even been to the 8wk appointment! She continued until she saw it was really making me mad/sad. Then she walked away mad at me. 
Am I wrong for this? Is it just emotions?
