Newly diagnosed thyroid


Hi, My doc asked me blood test for my fertility test. Today I went to Doc, she said, all tests are normal except Thyroid. My thyroid test was 18, she said normal range is max 5.

She prescribed me Levothryoxine 50 mcg. And said that I'll have to come after 3 months for blood test.

My question, after my thyroid level comes to normal, then I am able to conceive?

Theoretically yes. But that is assuming that your thyroid is causing the problem.

Its a slow business getting the thyroid straight. You may need dose increases before your levels are perfect.


Biiyyaa 3 months is too long to retest, arrange a test for 6-8 weeks after starting Levo. Arrange the earliest possible appointment of the morning for blood draw, fast overnight (you can have water) and leave off Levo for 24 hours. This gives the highest possible TSH which is what is needed when looking for an increase in dose or to avoid a reduction.

Re-testing/increases in dose should be repeated every 6-8 weeks until you feel well and your symptoms abate. From what I have read your TSH should be below 2 for pregnancy.

Ok, I'll talk to my doctor. Thanks both of you :)

Yes, you need a TSH of below 2 to get pregnant.

Look at & buy her book on pregnancy with an under active thyroid. Most GP's don't understand what you need to do to get pregnant & stay pregnant.

I like to add selenium to that list. Se is essential to catalyze the conversion of T4 to T3. It's the latter you need to feel well.
