Hello and welcome to HCM, Abortion is not the cause of failure to conceive subsequently. Inability to conceive has many reasons. First of all, you have identify those days in your menstrual cycle when the chances of conception are maximum i.e. during ovulation. The period of ovulation can be determined by basal body temperature and changes in the cervical mucus. If conception does not take place even after taking care of the ovulation period, you need to get some investigations done. In your case, complete examination of the reproductive tract - ultrasonography and/ or hysterosalpingography , hormonal levels -estrogens, FSH and LH levels and follicular sac. In case of your husband, semen analysis should be under-taken. These are some of the investigations which will let your gynecologist know the cause of inability to conceive and thus plan management. Thanks and take care Dr Shailja P Wahal
