It sure doesn't hurt to get a checkup in my opinion.. because you're right, if you have an underlying thyroid condition - it'll be next to impossible to lose weight until it's dealt with.
And if you get a clean bill of health, at least you can put your mind at ease. Yes, it sucks to have such incredibly slow weight loss (as I can certainly attest!), but like you, I am feeling so much better and am so much more activie than I used to be. So celebrate your successes whatever they are, and trust that the rest will come in time.
