For moms with more than two babies

So I am currently pregnant with number three. This is my fourth pregnancy, but we lost the last baby. I don't know what the deal is, but I'm not that excited. I'm very happy that we're having another baby, and I prayed and planned for this one, but now that it's actually here it's kind of like whatever. On top of that I found out I'm having a girl after two boys and it doesn't seem like that big of a deal to me. I feel like all of my friends and family are way more excited than me. I know a small part of it is because I've been dealing with a lot of sickness this time around, but I'm wondering if I'm the only one feeling this way? I am 15 weeks 5 days
