In early pregnancy, a pulsating sensation in the abdomen is the fetal heartbeat.

In early pregnancy, abdominal pulsations may be due to the fetal heartbeat, or they could be symptoms of other medical conditions. The most common cause of abdominal pulsations in early pregnancy is fetal movement, which can begin during the early stages of pregnancy and become more pronounced as pregnancy progresses. However, such sensations may also indicate conditions such as abdominal muscle strain, abdominal injury, peritonitis, uterine fibroids, endometriosis, ectopic pregnancy, or ascites. Pregnant women experiencing abdominal pulsations should seek timely medical evaluation for proper diagnosis and treatment.
