If you are expecting, the general recommendation for making prenatal appointments with your OB/GYN is to use the following timetable: • Between weeks 4 to 28: one prenatal appointment per month • Between weeks 28 to 36: one prenatal appointment every two weeks • Between weeks 36 to 40: one prenatal appointment per week In addition to prenatal appointments, some other check-ups may be required, such as ultrasounds to evaluate the baby’s growth and development and also assess the amount of amniotic fluid in your womb. Furthermore, if you have a multiple pregnancy, your OB-GYN may recommend more frequent prenatal appointments.
