Don’t have anything for baby….

I am almost 18 weeks and I don’t have anything for my baby besides a couple outfits. Is that normal? I feel pretty underprepared. I don’t have any money to buy anything for the baby right now. I don’t get paid maternity leave so I’m trying to save so I can take time off work to be with my baby since this is my first and probably only. I’ve only managed to save $200 so far because we’ve been struggling a bit. I’m feeling overwhelmed and nervous. And I’m sure people will tell me I shouldn’t have gotten pregnant, it was an oopsie. I was on the pill.
