At 28 weeks I started to go every 2 weeks to the doctor but it just depends on the doctor and your situation.
My Doctor Does It At 28 Weeks. I'm 28 Weeks Tomorrow And Have A Doctor Appointment Thursday..
I started going to the doctor every 2 weeks at 30 weeks!
I'm a high risk mommy and I've been going once a week since 18 weeks
Depending on your doctor but normally around 32 weeks that's what my paper says
