Hi.. From Past 2 years am suffering from hypothyroid.. Having tablet on a regular basis.. 3 months back my tsh was 0.99 i continued having tablet thyronorm 50mcg. Recently checked my tsh and the reading was 8. Though the reading is 8, am having regular periods. Now my question is tablet of how much mcg should i have? Or Should i get my test done again? Please help me out..
