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

First ultrasound showed healthy fetus, second ultrasound no fetus or heartbeat. Did I have a miscarriage?

Exact answer needs .: Details and review of the images. Given what you describe, and assuming no mistake with the first ultrasound (meaning there was an embryo), then the lack of a viable embryo/fetus would mean a miscarriage during the interval. Please discuss with your ob/gyn. A blood test of the pregnancy hormone (HCG) can be performed twice a couple of days apart - if decreasing, would confirm pregnancy loss. ...Read more
