No reaction when i told am pregnat!

My husbands grandma didnt react so much and she is always happy but today she is so angry not about my pregnancy but she should be happy and forget problems. My mother in law said congratulation and she didnt react so much.... my brothers in law didnt say congratulation until their mother told them and they said ah oh sorry congratulation ... dead no reaction , but my sister in law is super happpppy but others no reaction ... it makes me sad! i expected them to be veeery happy 😢
