If an ultrasound reveals something that looks like the forming of a sac but the blood test came back negative could you still be pregnant?
No; by the time the sac is visible on ultrasound, there would be detectable levels of Hcg in the blood and urine.
When can you visualize yolk sac on ultrasound?
You should be able to see the yolk sac at 5 weeks.
3 weeks after embryo transfer with a positive pregnancy test but no sac on ultrasound.Is this possible or is it too early to do an ultrasound?
You wouldn't normally see a sac on ultrasound until about 5 weeks. Sounds normal.
What does the passing of a fetal sac look like?
when i had my first miscarriage the fetal sac came out in the toilet and it looked like a little veiny blood sac. it was really small almost like a bubble.
How do you know if you had a chemical pregnancy?
Only a doctor can diagnose this with an ultrasound. The body will think you are pregnant but the ultrasound will show up an empty sac or nothing.

It depends on how far along you are. Ultrasound normally can detect a yolk sac between 5- 7 weeks. Kristin, RDMS
How does look?
Vessicles are sac like structures. They are made of a lipid membrane.
Vaginal ultrasound at 7 weeks no baby I am measuring 5 weeks but could it be a miscarriage and they aren't telling me i go back in 2 weeks for another ultrasound?
I understand what you are saying when you say messuring, they messure the sac and it calculates what the size is to get the age of the sac/fetus.
Is your first ultrasound after in vitro fertilization vaginal?
It is called a transvaginal ultrasound. A new pregnancy typically cannot be visualized until the HCG levels reach between 4,000-5,000. This is when the gestational sac, fetal pole and yolk sac can be visualized. Cardiac activity is typically not seen on an ultrasound until 6 to 7 weeks gestation.
When is yolk sac formed?
Most typically, the yolk sac develops around week 5 or 6 and can sometimes be seen on ultrasound this early.
How does vescicles look?

Can an internal ultrasound detect pregnancy before implantation?
From just over 5 weeks, see the associated website I had my first u/s done at less than five weeks I was probably 4.4 weeks, but all I showed was the yolk sac and the sac....no fetal pole or baby. == an internal ultrasound can detect a pregnancy much sooner than an external ultrasound, even if all it detects is a yolk sac.....there would not be a yolk sac if you were not pregnant.
