Tightness and hardness of the stomach at 29 weeks of pregnancy are considered to be contractions in pregnant women. These contractions may be physiological pseudocontractions or signs of preterm labor, and the patient needs to judge them in relation to the specific symptoms. In late pregnancy, if a pregnant woman is overly tired, such as standing or walking for a long time, physiological pseudocontractions may occur, which are usually irregular and have long intervals and usually do not require special treatment and disappear naturally after sufficient rest. In this case, there is also a small amount of redness or vaginal fluid, so you should seek medical help to suppress the contractions and carry out fetal preservation treatment. At the same time, it is recommended that the pregnant woman should lie on her left side, rest properly, and give oxygen therapy if necessary. After 28 weeks of pregnancy, you should learn to monitor fetal movement by yourself, and consult your doctor if you have frequent fetal movement or too little fetal movement. Take proper supplements of calcium, protein and other nutrients, and do not eat too greasy food and sweet food to prevent the fetus from being too big and not easy to deliver. Also prohibit sexual life to prevent stimulating uterine contractions and triggering preterm labor.
