My chihuahua had 4 puppies about a week and a half ago n now she has some brown discharge coming out \?

Mom may have a discharge in small amounts up to about 7-8 weeks after giving birth.
It may be greenish, brown or even bloody looking.
The discharge will not have an odor,so if you are noticing an odor or mom is acting like she is not feeling well, her appetite decreases, quits nursing, basically anything odd, call your vet immediately.
So how is she doing with them, feeding and cleaning?
Are all the pups nursing and growing?
