Is a pulse beating at the wrist a sign of pregnancy?

Under normal circumstances, the pulse felt at the wrist is typically a normal physiological phenomenon and not a sign of pregnancy. The detailed explanation is as follows:

The pulse detected at the wrist is actually a manifestation of the heartbeat transmitted through blood flow to the peripheral blood vessels. Normally, the heart beats rhythmically, pumping blood throughout the body. As blood flows through the arteries in the wrist, the elastic arterial walls expand and contract with each surge of blood, creating a rhythmic pulsation—this is what we call the pulse. Pregnancy involves multiple stages, including fertilization, implantation, and embryonic development. Early signs of pregnancy usually include missed menstruation, breast tenderness, nausea and vomiting, increased fatigue, among others. Therefore, there is no direct causal relationship between the pulse at the wrist and pregnancy. If one suspects they might be pregnant, the most accurate method is to take a pregnancy test, such as a urine pregnancy test strip or a blood HCG test.

Since everyone's physical condition and responses differ, it is not reliable to determine pregnancy solely based on sensations like a pulse at the wrist or other non-medical methods.
