Pregnancy

So I'm 17 weeks 2 days with #2. Am I the only a little worried about being pregnant? Like something may happen to the baby? I don't have a bad feeling or anything, it's just me being a little worried and thinking what if. Idk. I can't describe the feeling. I don't remember how I was with my first. He's 4 years old, so that was a long time ago lol. But someone please tell me I'm not the only one.
