Waiting for three months to repeat the test is appropriate. Your doctor will advise you if consultation with an endocrinologist is warranted.

Low T3, T4 and normal TSH imply problem with pituitary gland. You need a repeated blood test to confirm these levels and if there is no change, you need an CT or MRI of the brain. I wonder if you have any symptoms or manifestations of thyroid or gonadal disorder.
