Should I be this hurt?

So long story short really. Yesterday me and my partner told his family I was expecting. We made sure this time to wait until we were in the "safe zone" to tell them with hopes they'd be excited and instead the first thing his mother said was "Be careful. I'm not happy I'm worried to lose this one" like I get it but fuck. I'm hopeful for my lil baby and they're doing so well. I don't wanna hear that. And his father is just like " good thing you waited to tell us this time around so we aren't disappointed when something happens" like? Am I overreacting for being upset? Idk. I'm trying to let it go and not stress but I damn near burst into tears...

On a happy note, my sister and I are 2 months apart in age (dad's side) I just found out she's pregnant and our babies are like a month apart too. Like I'm so fucking excited 😭😭😭 I'm not alone no more!!
