Pregnancy does not result in wrist fluttering, but a change in pulse can usually be seen at 6 to 7 weeks, and an HCG test is recommended to determine if you are pregnant. A change in pulse can occur at 6-7 weeks of pregnancy, but it does not cause the wrist to throb. Slippery pulse can be seen at 6~7 weeks of pregnancy, but this symptom can also be seen in normal people or during menstruation, so it is not accurate to judge pregnancy by pulse. You can go directly to the hospital for HCG test, combined with clinical judgment of pregnancy. Generally, pregnancy can be determined by blood HCG test about ten days after intercourse. Therefore, it is not scientific to judge pregnancy by pulse. It is recommended to go directly to the hospital for relevant examinations and diagnosis, and to follow the doctor’s instructions to take regular pregnancy tests during pregnancy.
