Scared

So I'm 26 and 5 weeks pregnant and I'm extremely scared.
It's my first child and I have no idea what to expect. I'm a worrier. So of course I think that something horrible will happen in the process or worse I'll end up dying during childbirth.
I know it's crazy but it's been weighing on me for weeks.
So please I'd love to hear your pregnancy stories maybe it'll help me through mine 
Thanks for the support
