Tsh. 007 cause my period to not come? Confirmed not pregnant through blood test with obgyn. Synthroid (thyroxine) has been adjusted before and I did not miss period

Yes. It looks as if you were overtreated with the synthroid, (thyroxine) and definitely being put in a state of hyperthyroid can cause changes in menstrual cycle. Good luck, hopefully with change in dose you will find your period returns.
