Question about hypothyroidism and hyperthyroidism?

I went to the dr because I've been on my period for 3 months. He had my blood checked and said my t3 and t4 levels were low. So I looked it up on line and it says that that's a sign of HYPOthyroidism. Also everything else I have is a symptom of HYPOthyroidism like excessive hair growth on body, weight gain, excessive bleeding etc. However my dr wants to do a ultrasound on my thyroid because he thinks it's overactive and I have HYPERthyroidism. I looked that up and I have none of the signs(I actually have the opposite of the symptoms). So my question is if my levels are low and I have all the sympotoms of
HYPOthyroidism why is my dr saying he thinks my thyroid is overactive and I have HYPERthyroidism? Also he gave me birth control to make me stop bleeding, but once my thyroid is regulated won't that regulated my period also?

I can't really change doctors. My husband's military so we're stuck with the base doctors, unless we can afford the copay to go off base(which we can't)

There are actually many symptoms to both hyper and hypo and the test results are confusing. Your Doctor most likely knows what he is doing when the test are final he will explain it all to you.

well, i have no idea. call me in a few...

The fact that your t3 and t4 levels are low is definitive of hypothyroidism. You need further testing to find out the cause of the hypothyroidism, because hypothyroidism is only a symptom. It's not a diagnosis. So your doctor is doing the right thing in getting you an ultrasound. You also need further blood tests for antibodies.

But it sounds like your doctor is not a good communicator if he has you confused like this. You should probably start looking for a better doctor now. Getting proper treatment for a thyroid problem is a nightmare. And you are off to a very bad start.
