My doctor said do it between 28-30 weeks.
That's weird. I'm 28 weeks tomorrow and they just gave me my paper.
My doctor have me my blood work paper and told me to go anytime before 28wks. she gave me my papers at 25wks so I had three Weeks to do it.
I don't think you absolutely have to get it done on a certain week leave a message for them to call you back that you need to reschedule your appointment
