whatever your doctor said is true. but there is no need to be afraid. even when it is an ectopic pregnancy it can be managed efficiently with medicines or laparoscopy in the modern era. an ectopic pregnancy will not cause pain bleeding etc. unless it is about to rupture. the second possibility is that of late ovulation with multiple pregnancies. pregnancy in that case will be seen late on ultrasound. you can just repeat beta hcg (human chorionic gonadotropin) after 48 hours to know about status and doctor will decide accordingly. the only caution is that if it turns out to be an ectopic pregnancy just follow your doctor's advice. for further doubts consult an obstetrician and gynaecologist online --> <link>
