Can you verify if those labs are for Free or Total T4 and T3? They are both quite low in their ranges. Methimazole is for hyperthyroidism rather than hypothyroidism, so if you have hypo symptoms, it's possible you no longer need the Methimazole.
If you have Graves Disease you came to the right place... Are you taking any anti-thyroid medication to keep that under control?
It's always a good idea to get copies of all your test results when you have blood work. Your doctor is obligated, by law, to provide a copy upon request.
The spotting could be a result of the Graves Disease or of the ablation. I had to have a D&C shortly after I began menopause to help stop erratic bleeding, but it didn't do any good. Your spotting could be related to, either, your Graves Disease or the ablation. You should talk to your doctor to make sure everything is okay.
Even though your doctor doesn't mention your hormone levels, that doesn't mean they are okay. They could still be overlooking something; that's why it's important to get copies of the lab reports and look for anything abnormal. Once I obtained copies of my labs, I found several things that had been overlooked by my doctors and realized that I could have been helped long before I was...
How long have you had hypothyroidism? What are your current thyroid hormone levels? Can you please post your most recent lab results? Your doctor should be testing periodically for Free T4, Free T3, and TSH. Please post reference ranges with any results, as ranges vary from lab to lab and have to come from your own report.
Do you know if the cause of your hypothyroidism is Hashimoto's?
I'm not sure what an "Ablazen" is... Do you mean "ablation"? If so, there are a variety of possible ablations; can, please, you tell us what you had done?
Periods can be very erratic when we go through peri-menopause/menopause.
