Hello doctor I am 30 and have a 2 year old baby, now we are trying for another baby, but I am unable to conceive. I got hypothyroidism in my first pregnancy and was taking 37.5 mg Thyroxine. Post delivery due to some reason I have discontinued taking medicine for 2 months. Since then I am taking 175 mg thyroxine and my thyroid levels are normal. Last December I got pregnant but it got aborted in February due to early fetal demise. After abortion my periods were regular for 4 months, but now they are not. My period got delayed for 3 days this month. Earlier my menstrual cycle was of 30 days but now it is 33-35 days. Kindly give some suggestion. (my first and second pregnancies were spontaneous pregnancies)
