New to this forum. Synthroid change question

I am 24 year old girl. I believe I have hyperthyroidism i tend to forget which one i have. I've been taking synthroid 50mcg every morning for almost a year I think and then been checking with blood results with endocrinogolist every three months. this last appointment two months ago, he told me to skip synthroid on Saturday and Sundays and see if theres a change.. I think the level was maybe too high in my blood work. Now its already almost been three months since that change. This month I didn't get period yet. On day 55 now. ( I have pcos so its always been irregular but the past year its been pretty regular) Last night I was very restless, my legs especially. and I have hot flashes, I think. I'm getting very hot randomly and its very uncomfortable. I'm due to go back to endocrinologist in two weeks so ill find out the results then but I just don't know what is going on with my body. I also have anxiety which adds of course. but is there is a connection with these symptoms you think to the synthroid and thyroid or its unrelated? I just want to know whats happening in my body.

If it is already three months then it is the time to perform blood work ( TSH , FREE T3/4) .

Good luck,
