What kind of detergent mommy use for baby n mom?

I want to use good not too expensive detergent for my baby girl that's coming in March  I'm 36 weeks and I still don't have any baby detergent. Im still getting things done one by one and I also need to wash all the new clothes for her before she arrives. (They said it's a good idea) any of you ladies do/don't wash new clothes?? I'm very sensitive too so I'd like to use it for me, baby and husband as well. What do you ladies recommend ?
