A huge number of women are diagnosed with thyroid. Mostly harmless, a thyroid disorder might affect the fetus's growth. This is the reason doctors usually monitor thyroid levels and ensure that the levels are controlled before giving the green light to women. So, if your doctor has said there is nothing to worry, that should be the final word. You should try to convince your wife with the logic behind thyroid, conception and the growth of the fetus.
a lot of women have thryoid and it is important to get absolutely fine, before trying to conceive. i would suggest that you tell her to not be stressed, as this can interfere with her hormones and aggravate the situation. thyroid is completely curable and with the right treatment and medication, she can be absolutely fine.
yes please get it treated first, as one health condition can lead to another. since your wife has not conceived yet, it is best to first make sure she is absolutely healthy. this will ensure she has a healthy and stress free pregnancy and both the baby and the mother are in the best of health.
