Frequent contractions at 30 weeks with complete placenta previa need to be treated according to their condition, such as birth control, hemostasis, etc., and early termination of pregnancy is required in severe cases. Because 30 weeks is not yet full-term, frequent contractions at this time, be alert to the presence of preterm labor. If you have placenta praevia, you need to observe whether there is bleeding and the amount of bleeding. It is recommended that you need to seek prompt medical attention, and under the doctor’s examination and the condition of the fetus in the uterus to choose the appropriate way of treatment to preserve the fetus. If there is no relief, then hospitalization is necessary for observation. If the contractions are very frequent and the vaginal bleeding continues to increase, observation is not recommended, and surgical termination of pregnancy can be chosen to avoid placental abruption, which can cause hemorrhage.
