40 days pregnant, what happened?

Pregnant 40 days see red time, to go to the hospital to do B-ultrasound examination. Because at this time whether it is to do vaginal color ultrasound, or do abdominal color ultrasound, can see the gestational sac. If you do not see the gestational sac at this time, you must test the chorionic gonadotropin and progesterone in the blood, according to the test value, determine whether you can see the gestational sac. Under normal circumstances, if the chorionic gonadotropin is 1500-2000 and miU/mL, the pregnancy sac should be visible on vaginal color Doppler ultrasound. If the chorionic gonadotropin exceeds 3000miU/mL on abdominal color Doppler ultrasound, the pregnancy sac can also be seen. If HCG exceeds these numbers, but the pregnancy sac is still not visible on B ultrasound, it is necessary to be highly alert for ectopic pregnancy. It is also possible to continuously detect chorionic gonadotropin. If it does not double within 48 hours, be alert to whether ectopic pregnancy occurs and need further examination.
