Newly diagnosed

Starlight • Expecting a miracle baby after a long road!
I was just diagnosed with hypothyroidism and started on Armour (which affects T3 and T4). She's starting me on 90 mg and not having me come back for labs and adjustments for 3 months. 
I've only been taking it 3 days, and I don't feel any difference yet, except maybe a little nauseated. I'm taking one pill 30 min before breakfast, and that's it. 
I read on stopthethyroidmadness that you shouldn't stay on a starter dose very long. Anyone have any suggestions I can bring back to my doctor? Or does this sound right?
