The Uterus During PregnancyDuring pregnancy, the uterus stretches and grows to accommodate the maturing fetus. It also maintains the proper environment for the fetus to grow in. The uterus also contracts rhythmically during intercourse to facilitate the passage of sperm through the cervix and deep into the uterus. Finally, the thick muscular layer of the uterus is responsible for pushing the baby out during childbirth.
Tipped UterusIn most women, the uterus is positioned slightly forward (anteverted) so that it is resting lightly on the bladder. It is held in place by ligaments and the pressure of the other pelvic organs. But, if you have a tipped (also known as retroverted) uterus, your uterus is angled backwards.
While this may sound concerning, in most cases, it is nothing to be concerned about. If you are having any other symptoms, like pain during intercourse or your period, let your doctor know. Occasionally, a tipped uterus may signal that something else is going on.
