Diagnostic Pregnancy 1st trimester Ultrasound        

The Ultrasound Markers for the 1st Trimester are not included (see Obstetric Ultrasound First Trimester with Markers)

Preparation:  If your pregnancy stage is within the 1st trimester (0 to13 weeks), you will need a full bladder for the procedure. You must drink between 4-6 cups of water, half an hour prior to the exam, and don’t empty your bladder until the end of the examination.
