Brief Summary:
The investigators speculate that ultrasound examination in the first trimester can accurately detect placental location. By performing both transabdominal ultrasound and later hysteroscopy on women with a first trimester missed abortions and comparing the ultrasound findings to those of the hysteroscopy the investigators will evaluate the performance of the ultrasound in detecting the placenta location.

Condition or disease Intervention/treatment Phase
Placenta; Implantation Other: ultrasound exam Procedure: hysteroscopy diagnostic Not Applicable

Detailed Description:
All women with a first trimester missed abortion who will sign an informed consent form will undergo an ultrasound examination. During the examination, the operator will assess the location of the placenta/sac insertion. After the performance of the ultrasound, the women will undergo hysteroscopy with a different operator who will be blinded to the results of the previous exam result. During the hysteroscopy the second operator will assess again the location of the sac insertion .The investigatorswill then compare the results of the two tests using the histeroscopy as the gold standard and evaluate the performance of abdominal ultrasound exam in the evaluation of placenta/ sac inserion.
