The top priority of getting married has been completed, and the next thing on the agenda is to have a baby. Couples who plan to have a baby hope to have a healthy and intelligent baby. So some friends want to know how long it usually takes for an ultrasound to detect pregnancy? Let's all learn about it with me.
1. Urinalysis is the most common method for detecting early pregnancy, and it can be tested at home or in hospitals using early pregnancy test strips. To improve accuracy, it is best to use morning urine testing. A positive urine test result indicates pregnancy. If it is negative, a retest should be conducted one week later. The test result is generally reliable, but to rule out ectopic pregnancy, it is still necessary to go to the hospital for examination. Doctors may also recommend a blood test, which is generally used within one week of the onset of menstruation, to determine pregnancy through a blood HCG test.
2. Using ultrasound to diagnose early pregnancy is the most accurate and reliable method. As early as 5 weeks of pregnancy, which is one week after the expiration of menstruation, a circular halo in the uterus, also known as the gestational ring, can be displayed on a B-mode ultrasound screen. The dark area inside the ring is amniotic fluid, and rhythmic fetal heartbeat can also be seen.
3. Basal body temperature measurement. The simplest and most feasible method is to lie in bed every morning and measure body temperature, which is called basal body temperature. Before ovulation, the body temperature is generally below 36.5 degrees Celsius. After ovulation, progesterone increases and acts on the temperature center, causing the body temperature to rise by 0.3-0.5 degrees Celsius. If the egg fails to fertilize, the progesterone will decrease and the body temperature will return to normal after about a week; If pregnant, the progesterone level remains high and the body temperature remains high. If the high temperature curve in basal body temperature persists for more than 18 days, early pregnancy can generally be confirmed.
The above is the relevant information about how long pregnancy can be detected by ultrasound. Once a woman discovers pregnancy, she should be mentally prepared for early pregnancy reactions and pay enough attention to her diet, daily life, and other aspects to lay a good foundation for conceiving a smart and beautiful baby.
