Instant oats for GDM?

I was just diagnosed to have GDM today :( only next week then consult with dietitian. At the moment, I am trying to plan my diet plan for my breakfast as I usually will get the simplest possible. Do you all know whether I can put instant oats (Quaker Oat) into my diet? I most likely will add a bit of milo powder to give the taste. Thanks. #advicepls
