These guidelines describe the indications and key elements of 4 major types of obstetric ultrasounds, specifically the first trimester ultrasound, standard second or third trimester ultrasound, and limited and specialized ultrasound examinations.

The first ­trimester basic ultrasound is typically performed to confirm a viable intrauterine pregnancy.

These include:* bleeding in early pregnancy* possible ectopic pregnancy* recurrent miscarriage* patient anxiety due to previous pregancy loss It’s important to note that there is no intervention available today to a woman who is already pregnant that will influence the rate of early pregnancy loss.

Monitoring pregnancies may reduce anxiety, prevent rupture of ectopic pregnancy, and avoid the unease in waiting for a miscarriage to declare itself, but it cannot provide information that will affect the pregnancy’s prognosis.

Without visualization of a yolk sac (or signs of a further developed pregnancy such as an embryo), the location of the pregnancy cannot be certain and further evaluation is warranted.

In some cases where a pregnancy test is positive but there is no clear intrauterine pregnancy or extrauterine findings concerning for an ectopic pregnancy such as an adnexal mass on ultrasound, a patient may have a “pregnancy of unknown location.” It is important to consider the clinical context of a patient without a documented intrauterine pregnancy to guide further management.

Your prenatal visits will probably be scheduled every month until 32 to 34 weeks.

Warnock has brought to the Web MD community throughout the years.In my short twenty years in practice, technological advances have come about that allow careful monitoring of pregnancies in the first half of the first trimester.These modalities have the potential to determine the viability of a gestation before any negative sign or symptom develops, and, if used properly they can prevent dangerous complications or reassure patients during uncertain times.But along with the technology and the good comes misuse and inappropriate interpretation that can do a lot of damage and cause a lot of worry in many instances.There are several reasons to monitor pregnancies during the first few weeks after conception.And to talk about pregnancy, you can find experts and members like you on the Web MD Pregnancy Exchange.Several times a week in my practice, and in my Internet roles at the Web MD Fertility Center and the Pregnancy Board at Web MD, I have the opportunity to deal with early pregnancies and patients who want or need to know if a pregnancy is progressing normally (or not).Ultrasound examination at this time aids in the clinical assessment of pelvic pain and/or vaginal bleeding in the setting of an early pregnancy because it can diagnose an extrauterine pregnancy or an abnormal pregnancy, such as a hydatidiform molar pregnancy, an anembryonic gestation or an incomplete versus complete abortion.A definitive diagnosis of an intrauterine pregnancy can be made when a gestational sac containing a yolk sac is visualized within the uterine cavity.This schedule is flexible, depending on your pregnancy.If you experience any complications between your scheduled visits, call your doctor immediately.
