Is intrauterine echogenicity an intrauterine pregnancy? This is not certain, because the absence of echoes in the uterus means that it is in the very early stages of pregnancy, when the gestational sac is not visible and there is no way to determine if it is an intrauterine pregnancy. If pregnancy is confirmed, you can go back to the hospital seven days later for an examination of the uterine adnexa and an ultrasound examination to see if the pregnancy is intrauterine. A blood test for human chorionic gonadotropin is the most accurate way to check pregnancy, and you can also use an early pregnancy test to determine if you are pregnant.
