In the second and third trimesters of pregnancy, a heartbeat-like pulsation in the abdomen is usually a sign of fetal hiccups. Fetal hiccups typically manifest as rhythmic, localized movements similar to a heartbeat and are considered a normal physiological phenomenon. During mid to late pregnancy, it's important to get adequate rest and avoid excessive fatigue. Regular prenatal checkups, including ultrasound scans and fetal heart rate monitoring at the hospital, are necessary to monitor the fetus's growth and development.
