Insufficient holding of urine may affect the invisible fetal heartbeat and buds.
An obstetric ultrasound is used to see if the fetus is growing on time. Obstetric ultrasound is commonly performed both transabdominally and transvaginally.
Transabdominal ultrasound requires the pregnant woman to hold her urine to fill up her bladder in the early stage of pregnancy, so that the uterus and ovaries behind the bladder can be lifted to a relatively high position, and the morphology of the uterine cavity and the condition of the gestational sacs in the uterine cavity can be observed more clearly on the ultrasound image display.
Therefore, insufficient holding of urine may affect the invisibility of fetal heartbeat and fetal buds. In this case, you can re-suppress urine sufficiently for transabdominal obstetric ultrasound, or switch to transvaginal obstetric ultrasound to clarify the fetal buds and fetal heartbeat.
