Question on Hypo pleeease!

How accurate are blood tests in detecting Hypo? My TSH levels were supposedly "normal" last time I did a test about a month ago and yet I have been suffering EVERY SINGLE one of the Hypothyroid symptoms for a few months now! Can I still have it without necessarily detecting it or are blood works the only way to find out? Shall I take matters into my own hands and assume I do indeed have it and self-medicate? I am not a big believer in the orthodox medical system anyway.

I am also doing a Candida cleanse and am aware that some symptoms of various issues may overlap.. As I said bloods came back normal for TSH and hormones as well. Which doesn't make sense, given the stuff we go through sometimes.

Any thoughts?

Thanks!
