Oh goodness, SK212, I completely feel your pain. I had no idea that there was anything wrong with me until I had a miscarriage 2 years ago and spent 9 months trying to conceive after that. My cycle went from 40 days to 3 months then I started having a bunch of little periods every 15-20 days. It was strange so I finally went in to get tested. I have been trying to conceive ever since. So I understand the frustration of trying to get pregnant. I have decided that I just have to be content with my 1 little miracle child so that if I ever do pregnant again I can be genuinely surprised.

I am sorry for your troubles and I hope that you get good news next week when you go back to your doctor.
I stay on 1 dose for 2-3 months. I always end up needing to go in to get tested because I can tell that my TSH has either gone up or down and that's when my doctor changes my dose. Since I am still newly diagnosed she said that we're still just trying to find the right dose. However, it seems that my thyroid goes through periods of functioning and periods of not functioning. I'm not really sure what to make of that and I don't know how it can ever be under control if it is constantly going up and down like that.
I love being able to talk to other people about this online because nobody else in my family really understands what I'm going through. They think, "Oh, it's just another thyroid thing." They don't understand just how exhausted I am. It's a miracle that I can even get out of bed some days. They think, "So what? I'm tired and I can still do my doings," but they don't know what real exhaustion is until they've felt it every day for 2 years and it's combined with muscle weakness, foggy thinking, uncontrollable shivering when it's barely even cold, trying in vain to conceive for 2 years, depression, and the complete inability to lose weight no matter how hard you try. So knowing that there ARE people who understand helps me to feel just a little better.
