If you have hypothyroidism
then you may be having some menstrual irregularities.Irregular menses causes problems in ovulation hence infertility
.You get your latest thyroid levels checked,if abnormal you will need medicines to correct it.This should regularise your menses.If not you will need medicines for that too.After that you will need ovulation induction
drugs.I suggest you see a gynaecologist and endocrinologist
for further management.
