I'm not sure whether I should go for a second opinion about this and would really appreciate any advice from anyone that's been through something similar.
About six months ago I had what I would describe as a surge of hormones - a huge increase in libido 
, and a flushed face and feeling like my skin was really hot. The period after that was really heavy and came about three days early (I have been like clockwork for the 27 years I've had periods. The next few months were the same - early and heavy. I went to the doctor and had blood tests done - my TSH levels were over 10 (T4 was normal) and my iron was really low.
I got told to take iron supplements for two months and then come back for another blood test where my thyroid antibodies would be tested as well - in the meantime I found I was experiencing other things that were a bit weird (I have anxiety issues but it ramped up hugely, my left hand would shake sometimes and I would get dizzy as well as being tired all the time).
I was retested and found that my TSH levels had dropped to 5.7, but my anti-TPO antibodies were 283 (normal range is 0-60), my doctor in the hurried 2 minute phone call said - so how do you feel? To which I responded - I'm okay, I can get out of bed and go to work but I know things aren't right. We ended the phone call with her saying that I can have a blood test every year to make sure I am not hypothyroid but that's about it.
I just feel like I am in a bit of limbo waiting for something to happen - I would rather not be on medication for life, but I don't really want a period every three weeks for the next however many years, and anxiety so bad that I get panic attacks amongst other things.
So should I go to an endocrinologist? Should I just leave it and see what happens? Anyone been through anything similar? I am in my late thirties and had a grandmother with hypothyroidism if that adds anything.
Thanks in advance for any advice!
