Girls, hello everyone! We're preparing for pregnancy, I had tests for thyroid hormones, TSH was elevated by two whole units. Now I'm taking euthyrox for two months, then only a control analysis will be done. We were planning to get pregnant in October on the cancellation of COC (prescribed by the doctor after N/ber for three months). Maybe someone has been pregnant with elevated TSH? Then just adjust the dosage of tablets? The endocrinologist said that I will take them anyway constantly and throughout the entire pregnancy. Is it really true that on the cancellation of COC it is easier to get pregnant?
