Key takeaways

  • Recognize early labor signs including regular contractions, lower abdominal or back pain, and mucous discharge with possible light bleeding.
  • Time your contractions carefully - head to the hospital when they occur every 5 minutes and last 40-60 seconds consistently.
  • Understand that active labor begins at 4-5 cm cervical dilation, with full dilation reaching 10 cm before delivery.
  • Prepare for variable labor duration as the first stage can last 8-14 hours and varies significantly between individuals.
  • Monitor the three stages of labor: cervical softening and dilation, baby's birth, and placenta delivery.

You're in labor when you experience regular contractions every 5 minutes lasting 40-60 seconds, accompanied by lower abdominal or back pain and mucous discharge. Active labor begins at 4-5 cm cervical dilation, progressing to 10 cm before delivery.

How do I know if I’m in labor?

There are several signs by which you can tell that you are starting labor. There are three stages of childbirth. During the first stage, contractions soften the cervix of the uterus. At this point, you will feel pain in the lower abdomen or back. Contractions are usually accompanied by mucous secretions. There may be a little blood in them, but you should not worry about this [1]. The second stage of labor is considered the birth of the baby and the third is passing of the placenta.

When to go to the hospital?

At first, contractions will be short and irregular — 30 to 40 seconds [2]. But as soon as they begin to repeat every five minutes and last for 40-60 seconds, you need to head to the hospital. During the examination, your doctor will determine how dilated you are. At 4-5 centimeters, labor is considered active. Before the baby is born, the uterus will open up to 10 cm [3].

Contractions can last 8-14 hours. It is impossible to predict the exact length of time a woman will be in labor. The initial stage of labor is different for everyone [4].


Frequently asked questions

Early labor signs include regular contractions causing lower abdominal or back pain, mucous discharge that may contain light blood streaks, and increasingly frequent uterine tightening. These contractions initially last 30-40 seconds and are irregular.

Go to the hospital when contractions occur every 5 minutes consistently and last 40-60 seconds each. At this point, you're likely approaching active labor which begins around 4-5 cm cervical dilation.

Labor duration varies significantly between individuals, with the first stage typically lasting 8-14 hours. The exact timing cannot be predicted as each woman's labor experience is unique.

The first stage involves contractions that soften and dilate the cervix from 0-10 cm. The second stage is the actual birth of your baby, and the third stage is the delivery of the placenta.

Light bleeding or blood-tinged mucus discharge is normal during early labor as the cervix begins to soften and dilate. However, heavy bleeding should prompt immediate medical attention.
