Well I'm assuming "the pill" is contraception and there's not much harm in stopping it as long as you didn't start taking it for medical reasons. Might as well try to go off of it, that way you can tell your dr whether or not it worked. Also many women I know have found that male dr's tend to not be as good at female problems- assuming everything is because of a uterus. (My sister in law was told her bowel issues from gluten intolerance was mid cycle pain, without being tested for anything.) So if switching the pill doesn't work and your dr is still being difficult, maybe swtich doctors?
They did test for that too but again he said everything is normal. I wasn't told what the actual results were or that levels of anything though. I'm not sure if I should try stopping the pill as sugguestions and then if it's continuing going back again to see another doctor, as I guess I would have then tried what this one has suggested, I personally just don't think it's the pill.
Did your dr test for anemia? If not you really should go back and ask for it.
Second thyroid test can be in the "normal ranges" and still give you miserable symptoms. It took me 12 years to convince my drs that the "normal ranges" weren't normal for me. This is actually pretty common too. I suggest you pop over to the thyroid disorder community and post your results. There's a lot of very knowledgeable people who have dealt with being shrugged off by many dr's before finding the right one and can help you figure out if the results are less normal than the dr suggests they are. You might need to switch doctors.
Besides that I don't know what else to tell you but don't give up. When you don't hound the drs they think it's livable and you're ok. The louder you are the more likely the are to actually do something about what they consider "minor problems" like extreme fatigue, lethargy, and headaches.
