Prenatal care: 2nd trimester visits

- Listen to your baby's heartbeat. At second trimester visits, you might listen to your baby's heartbeat using a Doppler instrument. The Doppler instrument detects motion and conveys it as sound, which allows you to "hear" the baby's heartbeat.
- Assess fetal movement. Tell your health care provider when you begin noticing flutters or kicks. This usually happens by about 20 weeks — or perhaps earlier if you've been pregnant before.
