  • There are three stages of labor. When you feel contractions and your cervix opens until it's 10cm across, you're in the first stage (fully dilated). The initial stage lasts 6-12 hours, or less if you've already had kids. The baby is delivered in the second stage, and the placenta is removed in the third stage.

Tips for Tips for making your pregnancy better

These suggestions may help you feel more in control of your pain and manage it:3

  1. If your contractions begin at night, try to sleep as much as possible through them — the rest will help you prepare for the delivery, and your cervix will dilate while you sleep.
  2. If your contractions start during the day, stay upright and active to assist the baby move down and open up your cervix. This may help to hasten your labor and lessen the need for painkillers.
  3. Experiment with different positions. Rock on a birth ball or lean on your partner's neck with your arms around his or her neck. Simply keep moving!
  4. Take a warm bath or shower — it's a tried-and-true pain-relieving therapy that's been around for thousands of years.
  5. Concentrate on your breathing. Now is the time to work on your breathing methods. Inhale deeply through your nose and exhale slowly through your mouth. Maintain a relaxed jaw.
  6. Request a massage from your partner and include them in your labor. Having their encouragement and reassurance will stimulate your body to manufacture more endorphins, which are natural pain relievers.
  7. To keep your energy levels up, eat something healthy like a banana or low-fat yogurt. Avoid fatty foods because they may make you sick, and sweet foods, since they will only give you a temporary boost before you crash.
  8. Maintain your composure and carry on. You will manage your labor and pain much better if you are relaxed than if you are stressed.
  9. Call your hospital or doctor if your contractions last at least 60 seconds and come every 5 minutes
