If a pregnant woman feels tingling in her lower abdomen in the third trimester, she must be alert to the presence of a preterm miscarriage. The stabbing pain in the lower abdomen in the third trimester may often be due to the pregnant woman’s strain, or to contractions triggered by excessive emotions. The first thing you should do is to rest in bed and see if the abdominal pain is relieved after rest. If the symptoms do not ease or even get worse, you should go to the hospital in time. In addition, some pregnant women may experience mild abdominal discomfort as their uterus grows and the ligaments around the uterus are stretched after pregnancy. You can observe the degree of pain, if this is the case, do not worry too much, just rest properly.
