Yes, your T4 level is fine. In the first trimester of pregnancy, the goal is to keep TSH below 2.5 to 3, and your TSH at 2.69 is within the acceptable range. Your T4 value (12.07) is also within the normal range for pregnancy, which means your current Thyronorm dose is working well. Continue taking the medicine regularly and repeat thyroid tests every 4 to 6 weeks, as dose adjustments are sometimes needed during pregnancy.

A TSH of 19.64 is high, which means your hypothyroidism is not well controlled right now, even though FT3 and FT4 are near the normal range. This can happen if the Thyronorm dose is too low or if doses are missed. You should see your doctor soon for a dose adjustment, and repeat TSH after 6 to 8 weeks. Do not stop or change the dose on your own, as proper control is important for your health.

A TSH of 5.99 after stopping Thyronorm shows her hypothyroidism is coming back. The safest approach is to restart the same dose she was taking before, take it daily on an empty stomach, and not change the dose on your own. Her doctor can check TSH again after 6 to 8 weeks and adjust the dose if needed.

A TSH of 7.4 indicates underactive thyroid (hypothyroidism), which can cause symptoms like fatigue, muscle aches, and body pain. You should see your doctor, as your thyroid medicine may need a dose adjustment. Meanwhile, gentle exercise, good sleep, and pain relief as advised by your doctor can help ease discomfort.

A TSH above 100 means severe hypothyroidism, so bringing it down to 7.01 is a big improvement, but it is still higher than normal. You should continue your thyroid medicine regularly, and follow up with your doctor; your dose may need a small adjustment to bring TSH into the normal range. With proper treatment, TSH usually comes to normal and symptoms improve.
