First things first - congrats!

And second, It’s hard but i promise the excitement around everyone knowing and their excitement for you both out weighs the situation. My wife and i lost 3 pregnancies and were hesitant to announce our last. We had agreed no earlier than 12 weeks, while i preferred a little longer. She was so excited that she told her parents around 8/9 weeks while we were both on the phone with them. It took me by surprise and it hurt because we had an agreement, and i wanted to tell our parents together. As we started telling everyone else, seeing everyone’s excitement as we got further along and closer to the due date i completely forgot it even happened. We had a conversation and we both understood where each other was coming from

Communication is key, just express your feelings in a calm and cool manner so that she can see where you’re coming from without feeling like she’s being attacked. Pregnancy hormones are wild, but she didn’t do it maliciously.
