Hashimoto's disease can cause both hypo and hyperthyroidism, if you have a positive test for TSIab , then you can be hyper also, since TSIab attach to TSH receptor of the thyroid cells and stimulate them, exactly like TSH .
Regarding nodules, some times they release hormones independently and cause hyper as a result .
When you have your tests results please do post them here and we will be able to help you further !
Best of luck ,
