When you experience stomach pains at 29 weeks of pregnancy, you need to observe whether the pain is severe and to observe the nature of the pain. Mild tummy pains, swelling, tingling or slight dropping sensation can occur during pregnancy and do not require any special treatment, and will improve with bed rest. However, if the pain is severe and paroxysmal, accompanied by uterine contractions, hardness and tightness, consider the possibility of pre-eclampsia, and go to the hospital for examination and treatment of abortion. 29 weeks if there are signs of miscarriage, the common medication for abortion is Ritodrine, which can inhibit the contraction of smooth muscle of the uterus and relieve smooth muscle spasm causing miscarriage. During the treatment period, bed rest is needed.
