I would say it's not really worth DP going with you. To be honest not many of the men do go.
Mine only ever went to one appt and that is when we was asking about the amnio and he wanted to know stuff.

Visiting is at 3pm. They have your appt late in the day i thought they stopped working at lunch time. If you want PM your mobile number and i will sms to let you know what room i am in.
