Your prenatal appointments will become more frequent in the second half of your pregnancy. Even if you are in good health, and your baby has been thoroughly assessed at the 20-week ultrasound scan (see What the scan reveals), it can be reassuring to have these regular checkups with the doctor.
The number of appointments you have will differ depending on whether you've had any complications, or whether you are having a high-risk pregnancy for another reason, such as a preexisting medical condition like diabetes. If it's a low-risk pregnancy, you can expect around 14 appointments unless there are complications. As a general rule you can expect to have prenatal appointments from now on: every 4 weeks until you reach 30 weeks' gestation, then appointments at 2-week intervals until you reach 36 weeks' gestation. From then on, you'll have appointments weekly. And if you pass your due date (see You are 11 Weeks and 2 Days), you'll need to see your doctor once or twice weekly However, you can contact your doctor if you have any concerns.
If you're expecting twins, appointments will be more frequent and will depend on the type of twins you're having: non-identical or identical. If identical, care will depend on whether they share any of their support system (see A shared support system).
