Hi, we are planning for a second baby. During my first pregnancy, my thyroid levels were under control. I would like to know what TSH level is ideal for conception. I had a checkup today, and my TSH is 3.11. Please advise

TSH 3.11 is slightly high for planning pregnancy. Ideal level is below 2.5. Adjust dose with doctor.

I had a missed miscarriage 3 months ago. I have attached my report. Will I need to take any medicine now as we have already started trying to conceive? My gynecologist says to take medicine for 2 months. Please suggest?

I received my blood test report for a free thyroid test. My FT3 and FT4 levels are normal, but my TSH is 10 microIU/mL. What does this mean?

Answered by Apollo Doctors

I have a thyroid condition and am taking medication, which keeps it under control. Lately, I have been experiencing frequent memory problems and difficulty recalling things or speaking clearly. This is affecting me both at work and personally. Could this be related to my thyroid, or should I consult a specialist? Please guide me.
