The cramping felt during uterus stretching is caused by the stretching of the ligaments that help to support the uterus, according to WebMD. One of the ligaments that supports the uterus is the round ligament, and this is often the one that causes the most pain while stretching. Pain from the stretching of the round ligament is felt during the second trimester of the pregnancy.
WebMD says the round ligament is connected to the front part of the womb and the groin. Under normal circumstance, this ligament tightens and relaxes slowly. During pregnancy, however, this ligament becomes stretched and strained. Sudden movements cause this ligament to tighten quickly, which leads to a jabbing feeling in the uterus.
The University of Maryland Medical Center states that lower adenoidal cramps and pains are not the only sensation women experience while the uterus expands. Some women get a tingling or numbness in the lower body as the growing uterus presses down on the nerves in the legs.Learn more about Reproductive Anatomy
