Hypothyroid questions

leiani • Happily engaged. We have been trying for 19 months. 2 months before we started trying I went into premature labor & lost my baby girl at 18 weeks.

What is the best medicine to take?

How long after you started medication did you get pregnant? (For those who didn't get pregnant until taken thyroid meds.)

Also I am thinking this may be a reason why I haven't been able to get pregnant again. Ttc for 18 months after having a miscarriage with our first baby.
