HR and temp are ok, noticed last 2 days lower though.. HR around 68 and temp 98 average.. Slight tremor in right hand today... Started period this morning. Have I increased to fast ? Lol I know my doses is ridiculously low

Were you taking Levothyroxine before you started T3?

Ferritin is low. 75-100 is optimal. I would supplement iron and take each tablet with 500-1,000mg vitamin C to aid absorption and minimise constipation.

No I haven't used any thyroid medication until now...I've been sick and disabled for 6 years. I'm taking iron and vit c plus some other supps... It's hard feeling worse😒 Hoping I can get some function soon. I know I've been running on stress hormones and now they are likely lowering a bit from the t3.. My temps and pulse are low so I'm not over medicated.. Perhaps body needs a lot of time to adjust.. I just need support because I've been so low depressed and isolated that when I start feeling worse it's scary.. I wanted to throw a chair through my window this morning... That's how high the frustration is.. However no energy to carry that out!
