Childbirth is the process of giving birth to a baby. It includes labor and delivery of the fetus and the placenta. The placenta is the organ that supplies food and oxygen through the umbilical cord to your fetus during pregnancy.

A full-term pregnancy is 40 weeks. Labor usually begins between 37 and 42 weeks of pregnancy. It is how your body prepares to give birth to your baby. Preterm labor can start before 37 completed weeks of pregnancy. It can lead to premature birth. Premature babies may face serious health risks.

Signs that you might be going into labor include:

• Regular contractions start to come closer together
• Leaking fluid or bleeding from the vagina
• Low, dull backache
• Abdominal (belly) cramps

The signs of labor, when labor starts, and the time it takes to deliver your baby can vary with each pregnancy. Call your health care provider if you have any signs of labor, even if it is before your due date.

Labor happens in three stages.

• The first stage begins with contractions. This stage could last for hours or days. It continues until your cervix has become thinner and dilated (stretched) to about 4 inches wide to allow your baby to pass through.
• The second stage is when you begin to push downward. Crowning is when your baby's scalp comes into view. Shortly afterward, your baby is born.
• The third stage is when you deliver the placenta, and your provider cuts the umbilical cord.

Sometimes, mothers need to have labor induced. Medicines or other methods are used to start labor. This is usually only done when the due date has passed or if a problem with the pregnancy risks the health of the mother or the fetus.

Mothers and their babies are closely monitored during labor and delivery. Delivery can occur either vaginally through the birth canal, or if there are complications, the delivery may be done surgically by a Cesarean section. This is when the baby is taken out through your abdomen (belly) and uterus.

The amount of pain during childbirth can vary based on the size and position of the baby, your level of comfort with the process, and the strength of your contractions.

Options for pain relief during labor and delivery may include:

• Medicines may reduce the pain, but they don't stop it completely.
• Natural methods ease pain without taking medicines. A few examples include using relaxation techniques, a birthing ball, massage, or taking a bath or shower.
• Combination of medicines and natural methods.

Discuss your options, risks, and benefits of pain relief during labor and delivery with your provider before your due date.

Childbirth is the process of giving birth to a baby. It includes labor and delivery. Usually everything goes well, but problems can happen. They may cause a risk to the mother, baby, or both. Some of the more common childbirth problems include:

• Preterm (premature) labor, when your labor starts before 37 completed weeks of pregnancy
• Premature rupture of membranes (PROM), when your water breaks too early. If labor does not start soon afterwards, this can raise the risk of infection.
• Problems with the placenta, such as the placenta covering the cervix, separating from the uterus before birth, or being attached too firmly to the uterus
• Labor that does not progress, meaning that labor is stalled. This can happen when
  • Your contractions weaken
  • Your cervix does not dilate (open) enough or is taking too long to dilate
  • The baby is not in the right position
  • The baby is too big or your pelvis is too small for the baby to move through the birth canal
• Abnormal heart rate of the baby. Often, an abnormal heart rate is not a problem. But if the heart rate gets very fast or very slow, it can be a sign that your baby is not getting enough oxygen or that there are other problems.
• Problems with the umbilical cord, such as the cord getting caught on the baby's arm, leg, or neck. It's also a problem if cord comes out before the baby does.
• Problems with the position of the baby, such as breech, in which the baby is going to come out feet first
• Shoulder dystocia, when the baby's head comes out, but the shoulder gets stuck
• Perinatal asphyxia, which happens when the baby does not get enough oxygen in the uterus, during labor or delivery, or just after birth
• Perineal tears, tearing of your vagina and the surrounding tissues
• Excessive bleeding, which can happen when the delivery causes tears to the uterus or if you are not able to deliver the placenta after you give birth to the baby
• Post-term pregnancy, when your pregnancy lasts more than 42 weeks

If you have problems in childbirth, your health care provider may need to give you medicines to induce or speed up labor, use tools to help guide the baby out of the birth canal, or deliver the baby by Cesarean section.

Taking home a new baby is one of the happiest times in a woman's life. But it also presents both physical and emotional challenges. :

• Get as much rest as possible. You may find that all you can do is eat, sleep, and care for your baby. And that is perfectly okay. You will have spotting or bleeding, like a menstrual period, off and on for up to six weeks.
• You might also have swelling in your legs and feet, feel constipated, have menstrual-like cramping. Even if you are not breastfeeding, you can have milk leaking from your nipples, and your breasts might feel full, tender, or uncomfortable.
• Follow your doctor's instructions on how much activity, like climbing stairs or walking, you can do for the next few weeks.
• Doctors usually recommend that you abstain from sexual intercourse for four to six weeks after birth.

In addition to physical changes, you may feel sad or have the "baby blues." If you are extremely sad or are unable to care for yourself or your baby, you might have a serious condition called postpartum depression.
