Is it weird?

Is it weird that I am not really that excited about being pregnant? I’m married and all but all my friends are happy that they’re pregnant and are more excited then I am about my pregnancy. People always ask me are you excited and I say nervous instead of excited cause I’m really not. I just don’t know. Sometimes I am but most of the time I’m not. I’m more depressed about it and me and my husband are not happy anymore at all so idk.
