From what I understand, you should see a fetal pole by that time. However, I would go back for another u/s in about a week to see if things have changed or not.
An ultrasound at 6 weeks should show a fetal heartbeat, if there was a fetal heartbeat you're not miscarrying.. It's probable you estimated your due date wrong.
bleeding, sometimes pain and cramping. All bleeding cannot be considered an immediate miscarriage. An ultrasound and fetal hearttones need to confirm.
Not miscarriage, more likely brain damage. It's called Fetal Alcohol Syndrome
i had an ultrasound when i was 6 weeks pregnant, but by ultrasound, the pregnancy measured to be 5 weeks, so no fetal pole was seen yet. i think the earliest fetal poles can be seen is about 6 1/2 - 7 weeks. hope this helps :)
Sometimes a fetal infection can be diagnosed using ultrasound.
Your rate of m/c is only about 5% since you heard a heart beat! Praying for you!
Ultrasound is used to diagnose fetal fifth disease.
Recurrent miscarriage can be caused by several factors, including fetal, placental, or maternal abnormalities.
Ultrasound?
Ultrasound pictures are a fantastic advancement in technology. One practical application of ultrasound is in the non-invasive monitoring of fetal development in pregnant women.
Fetal heartbeat
Fetal monitors, Doppler fetal monitors, are handheld ultrasound transducers used to detect the heart beat in fetuses. They can be purchased online from DH Gate, Amazon and Baby Center.
