Major depression while pregnant

So I’m about 10 weeks pregnant, and for awhile I was super thrilled that we were pregnant with our first kid. But a couple weeks ago, I started having these second guessing thoughts. Like, “are we too young to be having a kid?” “We’ve only been married 9 months, is it too soon?” to the point that I just opened up to my husband, saying that I almost feel like i regret getting pregnant.

Did anyone else go through this? I feel like everyone is so much more excited for this baby than I am, or that they care more than I do. And it’s scaring me. I don’t know how to handle this...
