Hello,
With the question "Is 7 weeks 3 days pregnant without a fetal heart is it dangerous? ", the doctor would like to answer as follows:
Whether your pregnancy does not have a fetal heart rate also depends on whether gestational age 7 weeks 3 days is calculated by ultrasound or calculated by the last menstrual day. When the pregnancy is more than 6 weeks according to ultrasound (the length of the baby's head and buttocks is about 5mm), the fetus has a fetal heart, if the size is over 7mm without the fetal heart, the fetus is not developing.
7 weeks 3 days pregnant, the length of the head and buttocks of the fetus is about 10 -15mm, if there is no fetal heart, the fetus will not develop. And if calculated according to the size of the amniotic sac, it is also a poor prognostic factor. If you calculate the last period, you still have to rely on ultrasound to see if the pregnancy is developing or not.
Therefore, you should go back to the doctor after 1 week to re-evaluate the fetal development to see if it is normal or not, from which the doctor will have the appropriate treatment for you.
If you still have questions about 7 weeks 3 days pregnant without a fetal heart, you can go to a hospital of Vinmec Health System for further examination and advice. Thank you for trusting and sending questions to Vinmec. Wishing you lots of health.
