Sonogram (Definition)

An ultraound, also known as a sonogram, is a painless and relatively inexpensive imaging test that utilizes sound waves instead of ionizing radiation. There are no side effects. Ultrasound can give us two-dimensional, and in some applications three-dimensional, images of structures and organs in virtually any part of the body. In addition to diagnostic uses, such as evaluating abnormalities in the abdomen, pelvis, and breast, ultrasounds are commonly used to guide needle and catheter placement in a variety of surgical ...Read more

Can prog. and estro. hormones change a suggestive unviable pregnancy at 5wk6days ultrasound? And why does pregnancy test still show positive?

Can prog. and estro. hormones change a suggestive unviable pregnancy at 5wk6days ultrasound? And why does pregnancy test still show positive?

No genetics do: Unfortunately, genetic incompatibility is the most common reason for miscarriages. There are two types of miscarriages, 1.) An Incomplete Abortion whereby the products of conception are ejected with bleeding immediately. 2.) Missed Abortion where the pregnancy is still present in the uterus, stops growing, the products are not "ejected"and the HCG hormone output stagnates or declines in value. ...Read more

I had to at home pregnancy test and a urine test at the office all positive but nothing shows in the sonogram. Why is this?

I had to at home pregnancy test and a urine test at the office all positive but nothing shows in the sonogram. Why is this?

Various reasons: You may be too early to show up on the ultrasound. If you are less than 5 weeks since your last period the sono might not show anything. If you have had any spotting then an early pregnancy may have been lost. If no bleeding and the blood HCG is over 1000 miu and still nothing in the uterus on sono, the possibility of an ectopic (tubal) pregnancy needs to be considered. Talk to your doctor. ...Read more

Confirm pregnancy: Have you had any vaginal bleeding in the last 2 months ? You may or may not be in the middle of a miscarriage, but without further proof, the pregnancy cannot be either confirmed or ruled out. A higher sensitivity pregnancy test( B-HCG level), high level fetal ultrasound, and a follow-up visit to your OB is advised, to find exactly what has happened in the last 2 months ...Read more

Been having vaginal bleeding for 27 days straight what can be the cause? Im on birth control, pregnancy test negative, waiting on sonogram results

Been having vaginal bleeding for 27 days straight what can be the cause? Im on birth control, pregnancy test negative, waiting on sonogram results

Hormonal abnormality: The causes of dysfunctional uterine bleeding are either hormonal or structural (like a fibroid). At your age I would strongly suspect a hormonal problem and not a fibroid. The ultrasound will rule out (or in) the structural abnormality. Do you have PCOS? If the ultrasound is normal your doctor will likely run multiple tests to determine what the hormonal problem is. ...Read more

Get full GYN exam: Positive pregnancy test means something somewhere in your body is producing the hormone HCG which is detected in the urine. That something can be a normal embryo in the uterus, an embryo outside the uterus (tubal pregnancy), molar pregnancy (incomplete embyo) or an HCG-producing tumor. All these possibilities need to be explored urgently. ...Read more

Can a blood pregnancy or ultrasound test be off by two weeks?

Can a blood pregnancy or ultrasound test be off by two weeks?

There are: statistical variations and ranges of normal for both tests, but it changes with the duration of pregnancy, so for example it would be highly unlikely for a normal 7 week pregnancy to be off by 2 weeks on US dating, but that would not be an unusual range later in the pregnancy. How far are you along? ...Read more
