Specific symptoms that made you suspect you were hyper? If the decision to temporarily eliminate thyroid med and then lower dosage was based primarily on your TSH, you should be aware that TSH is very frequently suppressed below range when taking adequate doses of thyroid med. That does not mean you are hyper, unless you have hyper symptoms due to excessive levels of the biologically active thyroid hormones, Free T4 and Free T3.
A good thyroid doctor will treat a hypothyroid patient clinically by testing and adjusting Free T4 and Free T3 as needed to relieve symptoms, without being constrained by resultant TSH levels. Symptom relief should be all important, not just test results, and especially not TSH levels. If you have been tested for Free T4 and Free T3 (not the same as Total T4 and Total T3, which are frequently done), then please post results and ranges shown on lab report.
Since your symptoms seem to relate to missing two weeks of your med, plus changes in your med dosages, it seems most logical that they are related. Were you symptom free previous to those changes? Also, please post the most current results from the bloodwork you mentioned, along with reference ranges shown on the lab report. Over what period of time did you lose the 20 pounds? Was this a good thing, or something you really did not want to happen?
