Can pregnancy be detected by ultrasound 6 days after menstruation?

Menstruation is delayed for 6 days, which is generally about 34 days after menopause, and in the case of pregnancy, which is about 5 weeks pregnant, ultrasound examination can generally detect pregnancy.
When a woman reaches 5 weeks of pregnancy, she can go to a regular hospital to receive an ultrasound examination to observe the presence of the pregnancy sac, and at this time, not only can the pregnancy be diagnosed, but also can be diagnosed with intrauterine pregnancy and exclude ectopic pregnancy. Therefore, it is recommended that after the diagnosis of pregnancy, women can go to the regular hospital to receive ultrasound examination to confirm the diagnosis of intrauterine pregnancy at about 5 weeks of pregnancy.
If a woman undergoes ultrasound in early pregnancy, she can observe a dark area in the uterus, and if she has no symptoms of abdominal pain, she needs to follow up and observe regularly. 1-2 weeks later, if the presence of yolk sacs in the dark area of the uterine cavity is observed, the diagnosis of intrauterine pregnancy can be confirmed.
In addition, during pregnancy, women need to actively undergo various periods of obstetrics and gynecology, and need to actively cooperate with obstetricians and gynecologists to deal with any problems found.
