During your second trimester, you’ll see your doctor or midwife about once a month, unless you need extra care.

You may also have a variety of tests and check-ups. 

Here are some examples:

Prenatal genetic screening blood tests and/or special ultrasounds (optional)

• Detects chances of genetic abnormalities.
• If you miss the first blood test (between 10 and 14 weeks), you may still have the second blood test (at 15 to 21 weeks).
• It’s best to have both blood tests when possible. This improves result accuracy.

Ultrasounds (18-20 weeks)

• Checks the baby’s development and position
• Provides estimated due date (helpful if you’re unsure about the date of your last period)

Glucose screening (24–26 weeks)

• Tests for gestational diabetes, which can be caused by hormonal changes
• Most women’s blood sugar levels can be controlled by diet, but some may need to take insulin injections. In most cases, gestational diabetes goes away after the baby is born.

Blood test (24–28 weeks)

• A shot of Rh immune globulin will be given to women who are Rh negative.

Tests usually performed at all prenatal visits include:

• blood pressure and pulse
• urine test
• fetal heart rate
• measuring your abdomen to check the growth of your baby
