Do color Doppler ultrasound for delayed menstruation

If a woman's menstruation is delayed during the pregnancy preparation period, it is very likely that she has successfully conceived. One week after the menstruation is delayed, she can go to the hospital for B-ultrasound or color Doppler ultrasound. This test method can clearly see whether there is an embryo in the woman's uterus. If the pregnancy halo is seen during the test, it means that she is pregnant. So how long after the menstruation is delayed is it appropriate to do a color Doppler ultrasound?

How long should the menstrual period be delayed before I can do an ultrasound?

The time for B-ultrasound detection of early pregnancy is usually about one week after the menstruation is delayed. You can go to the hospital for a B-ultrasound examination to see if you are pregnant. If you can see the pregnancy halo under B-ultrasound, it means you are pregnant. The main purpose of early pregnancy ultrasound examination is to confirm intrauterine pregnancy. Exclude ectopic pregnancy and trophoblastic disease, estimate gestational age, and exclude pelvic masses or uterine abnormalities. Generally, a gestational sac can be seen in the uterine cavity 35 days after menstruation. At 6 weeks of gestation, the embryo and primitive heart tube can be seen beating.

How to detect pregnancy after delayed menstruation?

The working principle of pregnancy self-test is to detect human chorionic gonadotropin (hCG) in human urine. Generally, the trophoblast cells begin to secrete trace amounts of hCG on the 6th day after the egg is fertilized, and blood hCG can be detected about 1 day later. This is the most sensitive method for detecting pregnancy, and a positive hCG reaction appears in urine later than in blood. Although many types of early pregnancy test strips indicate that women can do self-tests for pregnancy one day after missing their normal menstrual period, in fact, the sensitivity of each test strip is different, and the test varies from person to person.

The above is an introduction to how long you should wait before doing an ultrasound. In short, after your period is delayed, you can first use the early pregnancy test to detect whether you are pregnant. After confirming pregnancy, ask your doctor when you can do an ultrasound.
