May I ask how your OB/GYN found thyroid nodules? Did you forget to wear your "THIS END UP" arrow for your annual PAP? Just kidding. However it was found, be grateful to know there is something wrong so it can be taken care of as soon as possible.
From my own very recent and very limited experience (so far), I can tell you I had the same frustration getting in to see an endocrinologist within a reasonable amount of time. The best way to get in earlier is not to make the appointment yourself, but demand your primary physician or the OB/GYN refer you to them directly. They will need to call the endocrinologist and tell them you need to be seen quickly. If that doesn't work, then maybe you need to search for other doctors in a different area if you can. Don't be afraid to consult a cancer specialist if you have any fears your nodules are malignant. I cannot imagine any doctor that would tell you there are nodules in your thyroid and not hurry you through to an endocrinologist. You deserve better care than that.
My nodules were discovered by accident through a carotid artery ultrasound, so I know the shock that comes in finding something you weren't looking for. Like you, my nodules were "hypoechoic;" I believe that means they are solid, not fluid-filled. Please visit the Thyroid Cancer website at http://www.thyca.org for information about the various kinds of nodules, etc.
Also, you can Google the medical terms you don't understand to learn there definitions.
Take care.
