It's a wonderful book. Also, and this is a little thing, but I've heard from others it is relevant as well. I completely stopped caffeine, and went to decaf. At TSH of 4, drinking caffeine, and not plotting or monitoring fertility signals, I wasn't pregnant. After less than two months of taking a higher dose of thyroid hormone and having a TSH of 1, tracking fertility signals via the Wechsler book and an excellent fertility awareness method monitoring chart , and avoiding caffeine, I got pregnant.
Some books say that having pre-existing thyroid problems increases miscarriage risk.
Others say if treated, the risk of miscarriage is no greater for a women with hypothyroidism. The reason, however, is unknown. For women with successfully treated hyperthyroidism, the risk of miscarriage is practically the same as a woman without a thyroid problem. But some of the perceived risk can be reduced by the mother's own actions. The Thyroid Forum is THE place to jump into the conversation.
