A significant pulse beat in the left hand is not a sign of pregnancy. To check whether you are pregnant from your pulse, you need to see a professional Chinese medicine doctor to cut your pulse. Self-perception of a significant pulse beat in the left hand alone is not a sure sign of pregnancy. The natural process of pregnancy should be properly understood. If you had sex before and did not take contraceptive measures there is a possibility of pregnancy, if you have sex during ovulation, the chances of pregnancy are higher in comparison, and it is recommended to take the appropriate auxiliary tests to confirm the diagnosis. The earliest and most accurate method is to take a blood test to check the level of human chorionic gonadotropin in the serum 10 days after sexual intercourse. Folic acid supplements are required in the first trimester.
