Family drama

Virginie

So, today was my 21 weeks US. The Tech wrote the sex on a paper. We Will find the Gender at my surprise baby shower organized by my sister and my mom. My sister would be the only one knowing the Gender. But, my mom wanna know it too. I said no, because more people know, higher are the risk of letting it slip. She got mad. Then, my husband said To leave me alone because It's our baby and i don't even know the Gender. My mother left the family group..

Is my mom over reacting or should did i ?

What should i do ?
