Hi! If you are three months late, take a beta HCG test in blood, and an ultrasound for confirmation. If these tests are negative then other causes of delayed or missed periods will have to be looked at such as stress whether emotional or physical, hypothyroidism, polycystic disease of the ovary, pituitary tumors secreting prolactin, anemia and poor diet, hormonal imbalance, unexplained or sudden weight gain or weight loss. You will need to consult a gynecologist for this.
