[/INST] Hi With hyperthyroidism, PCOD and irregular periods , pregnancy is usually difficult because women with these conditions do not ovulate regularly. Having said that, ovulation does occur occasionally and if you are overdue for your periods you should do a urine pregnancy test.Let me know if you have any other queries. Thanks </s>
