When you are pregnant with fibroids, you usually do not experience contractions. Because fibroids usually grow in locations such as the muscular or submucosal layer of the uterus, these types of fibroids usually do not cause abdominal pain or contractions. If fibroids degenerate, they may cause abdominal pain, irregular bleeding, or fever, but they do not directly cause uterine contractions. If the fibroid is large, it may press on the space for the fetus to grow or cause premature rupture of the membranes or abdominal pain, but it does not usually cause contractions. If symptoms such as uterine contractions occur, it is necessary to consult the doctor in time for examination. If regular contractions occur, it is necessary to carry out birth control treatment to avoid preterm labor.
