The key is to determine the duration of the pain and the interval of time. If the vague pain lasts only 10-20 seconds with an interval of 5-6 hours, it is not necessarily a birth, but an irregular contraction of the uterus in late pregnancy, so there is no need to be anxious. If you have vague pains with redness or vaginal water, you should go to the hospital. You should also pay attention to lying on your back and elevating the breech position to avoid low amniotic fluid due to vaginal water. If the contractions last for 30-40 seconds and continue to occur at intervals of 5-6 minutes, and the frequency of pain is increasing, it is really time to give birth.
