Women need to undergo early prenatal check ups after pregnancy, and the commonly used examination method is gynecological ultrasound. However, for women who are becoming expectant mothers for the first time, they do not have any pregnancy experience, so it is unclear how long after pregnancy they can go to the hospital for examination. So, when is the first ultrasound done during pregnancy?
The number of days a woman needs to undergo her first ultrasound during pregnancy depends on her menstrual cycle. The average menstrual cycle is around 28 days, so women usually undergo their first ultrasound examination between 42 and 56 days after pregnancy. If menstruation is frequently delayed, it should also be postponed according to the timing of the menstrual cycle. Therefore, women should be aware of their menstrual condition in their daily lives.
At around 45 days of pregnancy, the size of the gestational sac is moderate. At this time, the first ultrasound is performed to mainly check the implantation of the gestational sac in the uterine cavity, determine whether there is a single or multiple pregnancy, and whether the size of the gestational sac matches the gestational age. During the first ultrasound examination of the first pregnancy, some expectant mothers can also see the fetal heart rate of the embryo, which can better understand the health status of early embryo development.
In addition, if a woman experiences slight vaginal bleeding or severe abdominal pain after pregnancy, she should promptly undergo ultrasound examination to rule out ectopic pregnancy or threatened miscarriage. Women who have had a history of miscarriage or miscarriage before should pay more attention to prenatal checkups after this pregnancy, and if necessary, increase the density of prenatal checkups.
