If a Miscarriage was spontaneous, without any prolonged or complicated
bleeding, it will not have any bearing on
ovulation. The reason for delayed
ovulation could be that during pregnancy the body is producing HCG, a hormone of the pituitary gland that suppresses production of other hormones to stimulate ovulation. With use of basal body temperature or cervical mucus monitoring to find out the most fertile period, you can return to a normal cycle of ovulation.
