Hello doctor! My menstrual cycle is irregular and recently I tested with a stick and it showed 2 lines, 1 dark line and 1 light line. I did a blood test and a transvaginal ultrasound and the doctor diagnosed me as pregnant but the beta HCG test index was a bit low at 259.7 and the gestational sac was not seen. Then 2 days later I had another blood test and the beta HCG index was still low at 239.7. The doctor said that the fetus was likely underdeveloped or ectopic and asked me to go home for further monitoring and scheduled a follow-up appointment in 1 week. After that, I had brown bleeding with coffee grounds and some pain in my left abdomen, sometimes dull, sometimes clear. I continued to go to another clinic and the beta index dropped to only 150.6 and the gestational sac was still not seen. So doctor, can you tell me if the beta HCG test is low and gradually decreases, brown bleeding, and left abdominal pain is an ectopic pregnancy or a miscarriage? I hope the doctor can advise and answer. I sincerely thank you!

Hello doctor, how many weeks old is a fetus when there is a heartbeat? My wife had an ultrasound and the doctor said the fetus is 8 weeks old but there is no heartbeat and said the fetus is stillborn. What does this mean?
