Introduction
The menstrual cycle is 25 days. Generally, after missing your period for 35 to 40 days, you can go to the hospital for an ultrasound examination. Note that during early pregnancy, a certain amount of urine must be retained in the bladder for clear visualization during ultrasound; therefore, pregnant women are advised to hold urine in advance. Before undergoing the ultrasound, avoid or limit consumption of gas-producing foods such as milk and sweet potatoes to prevent interference with ultrasound wave transmission and unclear imaging.
A menstrual cycle of 25 days is normal. Generally, you can go to the hospital for an ultrasound examination about 35–40 days after your period has stopped.
Pregnancy itself involves a process, and if detected too early, the gestational sac may not yet have entered the uterine cavity or may be too small to be seen on ultrasound. Under normal circumstances, it's more appropriate to perform an ultrasound at six weeks or later of pregnancy. An ultrasound can confirm whether pregnancy has occurred and whether the location of the gestational sac is normal. As early as five weeks, an intrauterine gestational sac may be visible on ultrasound. By six weeks, fetal cardiac activity can usually be observed, indicating that embryonic development corresponds with gestational age. Around five months into the pregnancy, an ultrasound is needed to check for any structural abnormalities in the fetus. Throughout pregnancy, multiple ultrasound examinations should be performed based on whether the mother has complications or the baby shows any abnormalities.
Before undergoing an ultrasound, wear loose, easily removable clothing and shoes. During early pregnancy, a certain amount of urine must be retained in the bladder to ensure clear imaging, so pregnant women are advised to arrive with a full bladder. Avoid consuming gas-producing foods such as milk and sweet potatoes before the ultrasound, as excess gas may interfere with ultrasound wave transmission and result in unclear images.
