The uterus is located at the bottom of the stomach, in the center of the pelvis, between the bladder and the rectum, and is shaped like an inverted pear, with the bottom of the uterus below the level of the pelvic inlet in the case of non-pregnancy. The uterus is located in the center of the pelvic cavity, often referred to as the “belly” area, the bottom of the uterus does not exceed the level of the pelvic inlet in normal cases of non-pregnancy, i.e., it is located below the upper edge of the pubic symphysis. In front of the bladder, behind the rectum, the lower end of the cervix is connected to the vagina, the left and right sides of the fallopian tubes and ovaries. When the bladder is emptied, the uterus is in a mildly anteriorly tilted forward flexed position. If you are pregnant or have a mass in the uterus, such as a uterine smooth muscle tumor, the uterus will enlarge and can be palpated above the pubic symphysis. The doctor can initially assess the week of pregnancy and the size of the mass by the height of the uterine fundus, which can be 2-3 transverse fingers above the pubic symphysis in the third trimester, 1 transverse finger below the umbilicus in the fifth trimester, and between the umbilicus and the raphe in the eighth trimester.
