Can I show my excitement?

My friend is pregnant again after multiple losses and I am so excited. I have been thinking about how happy I am for her all day. I am scared though, and I don’t know how to explain this well. But I don’t know if it’s okay for me to be this excited or to show how excited I am.

I am not saying that I’m scared she will have another loss. I told her that every pregnancy she has is reason to celebrate, she’s excited too. I genuinely believe that she will get her baby. I just haven’t shown how excited I am. I’ve shown excitement but she doesn’t know that I think about it randomly and jump up and down. She doesn’t know the extent of the excitement. i haven’t ever experienced loss and I know it hurts and I don’t wanna do something wrong.

And please don’t take this wrong, she is so dear to me and I don’t want to make her feel something negative. She’s dealt with enough as it is
