Question 1

can an ultrasound miss a pregnancy 6-7 weeks along?

Accepted Answer

Depends: A transabdominal ultrasound (from your belly) can miss or not see the pregnancy. This is due to limitations of the technique. However a transvaginal ultrasound would not.

Question 2

can a pregnancy ultrasound miss a twin? i had an early (8 weeks) ultrasound and the doctor said she couldn't rule out twins at this point.  could another baby really be "hiding"?  only one heartbeat detected, so i don't know what to expect.

Accepted Answer

This : This can occasionally happen, but it is a very rare occurrence.  The experience of the imager is also an important factor to consider. If the examination was performed by an inexperienced ultrasound technologist, they may have been confused by some aspect of the anatomy and questioned the possibility of a twin pregnancy. There are a limited number of places that a baby could "hide" within the uterus; therefore, an experienced ultrasonographer is very unlikely to miss a multigestation pregnancy with two or more fetuses.

Question 3

can a transvaginal ultrasound miss an early preganancy or urine test ? i went to the er and doctor say everything look good no preggo.

Accepted Answer

Ultrasound: the ultrasound can only show If something big enough for  it to image a fresh pregnancy is probably too small so pregnancy test in the near future if you had a missed period would be the best test two give you an answer then you can follow up with your ultrasound

Question 4

is it possible for a vaginal ultrasound to miss a pregnancy at 10 weeks?

Accepted Answer

No: A 10 week pregnancy in the uterus would not be missed on ultrasound.

Question 5

do cryptic pregnancies exists? can you have a positive urine test with negative blood tests and negative ultrasound? when does a babys face appear in an ultrasound?

Accepted Answer

: If the tests are done correctly, you cannot have a positive urine test and a negative blood test. Ultrasound may be negative if done too soon.  Ultrasound can detect an embryo as early as six weeks into the pregnancy. Vaginal ultrasound can show face at 11 weeks of pregnancy.
Cryptic pregnancy is not a medical term.

Question 6

can a transvaginal ultrasound miss a 16 week pregnancy?

Accepted Answer

No : Transvaginal us should not miss 16 week pregnancy

Question 7

could a vaginal ultrasound miss a pregnancy 8 weeks after encounter even if you bladder was not empty?

Accepted Answer

Very unlikely: Anything is possible, but a transvaginal ultrasound should be able to detect an 8 week pregnancy most if not all of the time.

Question 8

how common are partial molar pregnancies among caucasians? can they be picked up on a an ultrasound at 5 weeks gestation? possible signs?

Accepted Answer

Molar pregnancies: Molar pregnancies are more common in Asian individuals and can be sometimes suspected by a rapid rise in the size of the uterus relative to known LMP gestational age. At 5 weeks of gestation it is very difficult to confirm a partial molar pregnancy as the ultrasound if done will show only early gestational material. A chorionic villus or amniocentesis sampling later in pregnancy will be abnormal.

Question 9

would it be possible to miss a pregnancy on transvaginal ultrasound if its been 10 weeks since last encounter?

Accepted Answer

Not likely at 10: Weeks. Even if you are only 6 weeks it is likely you'll see the embryo on ultrasound, if there is pne there.

Question 10

could obgyn miss a 8 weeks pregnancy at routine vaginal ultrasound when there was no suspicion? thank you very much. ?

Accepted Answer

: Why was the ultrasound done? It is possible but unlikely that competent ultrasound examination would miss an 8 week pregnancy.
If you have any concern, do a home pregnancy test that would be positive.
