Patient's question:
Detailed medical condition and consultation purpose: Online says pregnancy symptoms appear at 5 weeks. Is 5 weeks calculated from the day of the last menstrual period or the day of fertilization?Doctor's answer:
During early pregnancy, sexual activity should be avoided. Early intercourse can easily trigger uterine contractions, leading to threatened miscarriage. At 37 days of pregnancy, the gestational sac is still relatively small, and it may not be visible in a general ultrasound examination. Urine or blood tests are usually required in this case, and urine tests are generally quite accurate.Recommendation: It is recommended that you undergo an ultrasound examination around 40 days after your last menstrual period to confirm intrauterine pregnancy. If you plan to continue the pregnancy, it is best to avoid sexual activity.
