How to calculate the time interval between contractions?

When a pregnant woman is about to give birth, she will experience uterine contractions. The symptoms are that the pregnant woman will feel her belly tightening and hardening, and abdominal pain will occur when the contractions are frequent. If water breaks or vaginal bleeding occurs, go to the hospital immediately. Pregnant women can record the time intervals between contractions to better judge whether they will give birth soon.

How to calculate the time of uterine contractions

1. When uterine contractions cause you slight pain, it passes after a while, and gradually the pain intensifies, the intervals shorten and the pain lasts longer. The contractions come like waves, and the pain spreads to the lower abdomen or there is a feeling of lower back pain and defecation. This kind of uterine contraction is in preparation for the birth of the baby, and expectant mothers do not need to worry too much. Considering the upcoming arrival of the baby, this little pain is nothing. Let’s learn about the interval between contractions.

2. At the beginning of labor, the interval between contractions is long, about 10 minutes, and the duration is short, about 30 seconds. As labor progresses, the interval time gradually becomes shorter, to only 3 to 5 minutes, and the duration gradually increases to 50 to 60 seconds. The intensity of contractions continues to increase, and when the cervix is ​​about to dilate, the interval time between full-time contractions is shortened to 1 to 2 minutes, and the duration can reach more than 1 minute. The continuous strengthening of uterine contractions forms an effective downward impact force, and the cervical opening expands from a diameter of less than 1 cm to a full diameter of 10 cm. At this time, the birth canal becomes a curved cylindrical wide tube. The fetal membrane usually ruptures at this time, and 300 to 500 ml of amniotic fluid flows out.

3. The most convenient way to check uterine contractions is to place your palms on the abdominal wall. During contractions, the uterine body will bulge and harden, and will relax and soften during the intervals. In addition, the contraction curve recorded with a Tianer monitor can also show the intensity, frequency and duration of each contraction. There are also some contraction timers available for download on the website, through which expectant mothers can understand their physical condition in a timely manner. Generally, the time of uterine contractions is calculated. If the number of contractions is around 10 per hour, it is considered to be relatively frequent and you should go to the hospital for a comprehensive check-up in time. If the contractions are not very frequent and there is no abdominal pain, they may be false contractions and you just need to rest.
