Thyroid sono results:"heterogeneous gland suggesting multinodular goiter -no discrete dominant masses observed"-what does this mean?

Lumpy! Opinions vary, but... Especially for women, thyroid nodules are very common. These are sometimes familial or inherited and are sometimes more common later in life. There is little to worry about, especially without a specific "dominant" nodule over ~1cm. You should get thyroid blood work and a followup ultrasound within a few months. If the gland is huge, you may need treatment.
Translation. Your thyroid gland is enlarged (that's what a goiter is). On ultrasound, some areas of your thyroid appear darker than others (that is heterogenous). There are nodules seen, but none is obviously larger than the others (this is what suggestive of a multinodular goiter means). If your thyroid is large enough that it's causing you symptoms, than see a surgeon about having it removed.
Possibly autoimmune. Heterogeneous texture is an ultrasound description of thyroid tissue that looks irregular, as if there are many small nodules. This is a common finding in people with autoimmune thyroid disease, such as hashimoto's thyroiditis. It is important to make sure that thyroid function is normal.
