Hashimoto's!: You could have Hashimoto's thyroiditis which is the most common cause of hypothyroidism and it is possible that some patients could have negative antibodies. In this case the symptoms are usually milder. Also a transient hypothyroidism could happen in woman after deliver so if you had a baby recently that could explain it

Unlikely: If you have not had an ultrasound of the thyroid, that can be reassuring if normal. Often times the thyroid stops working or slows down.
