How to tell less than thrilled in laws?

My in laws prayed that I would have a miscarriage and told me to terminate my pregnancy when I was pregnant the first time and essentially told my husband (then fiancé) that he could move back in with them and leave me. They borderline disowned him and the reason why they didn’t was because we lost our baby girl. That was 4 years ago, and we have been having the most difficult time getting pregnant since. How should we go about telling them we’re expecting? It’s the end of the world for them but then his mother is all offended when I don’t include her in anything and I’m not excited to share life things with her. She called my husband crying back in November saying I hate her and she just wants me to be like her own daughter and I don’t try hard enough. In this same phone call she said that I’m never going to let her see her grandchildren and I need to name our first girl after her mother. I’m so stressed over this especially since they live three hours away and my family is 10 hours away. My plan for my family is to surprise them with little eggs that have a message inside. Should I do this with my in laws as well? I have no idea how they’ll take it.
