Breast Feeding with Humira

Me

So I have an auto immune disease and have to be on Humira, I was wondering if their is any other women on here that have ever breastfed while taking it, my OB says it's fine but my GI is telling me that their have been studies shown that there is a small amount found in breastmilk and she told me it's our choice if I want to breastfeed. But I wanted others opinions too.
