Frequent Questions

Do I need to have a full bladder?

A:If you are in your first trimester (1-12wks) it is recommended that you have a full bladder for testing. Drinking 16-24oz of water ½ hour prior to your appointment is encouraged. Patients for CVS testing also must have a full bladder. If you are scheduled with a genetic counselor prior to your ultrasound appointment, there is no need to arrive with a full bladder.

Can I bring my children?

A:We encourage you NOT to bring any children less than 12 years of age with you for your office visit. If you do bring them, you must have another responsible adult with you to watch over them in our waiting room as they are not allowed in the exam room. If you have any further questions about this, please contact us by phone.

How many people are allowed in the exam room?

A:Due to limited space in our examination rooms, no more than 2 people may accompany the patient.

Do I still need to see my OB/GYN?

A:Yes! We partner with your OB/GYN to provide you with specialized care.

What do I do if I am bleeding?

A:Please call your OB/GYN first and they will direct you with how to proceed.
