Overview Braxton Hicks contractions During the second and third trimesters of your pregnancy, you may notice times when your belly tightens and becomes firm to the touch and then relaxes. These are called Braxton Hicks contractions. Think of them as "warm-up" exercises for your uterus.
These contractions may be so mild that you rarely notice them. Or they may be strong enough to make you stop what you are doing.
You may begin to feel Braxton Hicks contractions between the 28th and 30th weeks of your pregnancy. But sometimes they start as early as the 20th week. You most likely will have more of these contractions during your ninth month.
It is often hard to tell the difference between true labour pains and Braxton Hicks contractions, especially in your first pregnancy. Braxton Hicks contractions:
Tend to be irregular and vary in strength. They do not become more regular or stronger. Go away when you're active. (True labour pains may continue or increase during activity.) Are more noticeable when you rest. True labour pains tend to last longer, become stronger, and occur closer together than Braxton Hicks contractions.
If you are not sure what type of contractions you're having, talk to your doctor or midwife.
Preterm labour Preterm labour is labour that comes too early—between 20 and 37 weeks of pregnancy. In labour, the uterus contracts to open the cervix (Figure 1) . This is the first stage of childbirth. In most pregnancies, this happens at 37 to 42 weeks. Preterm labour is also called premature labour.
It can be hard to tell if preterm labour starts. You may have regular contractions. This means about 6 or more contractions in 1 hour, even after you've had a glass of water and are resting. You may have other symptoms, such as menstrual-like cramps or leaking or gushing of fluid from your vagina.
Call your doctor or midwife if you have any of these signs of preterm labour.
First stage of labour and delivery The first stage of labour is divided into three phases: early labour, active labour, and transition.
Early labour Early labour is often the longest part of the birthing process, sometimes lasting 2 to 3 days. Contractions:
Are mild to moderate (you can talk while they are happening) and last about 30 to 45 seconds. May be irregular (5 to 20 minutes apart) and may even stop for a while. Open (dilate) the cervix It's common for those in early labour to go to the hospital and be sent home until they are in active labour or until their "water" (amniotic sac
Active labour Active labour starts when the cervix is about 5 to 6 cm (2 to 2.4 in.) dilated. This stage is complete when the cervix is fully effaced and dilated (Figure 2) and the baby is ready to be pushed out.
During this phase, contractions get stronger, are more frequent (every 2 to 3 minutes), and last longer (50 to 70 seconds). Now is the time to be at or go to the hospital or birthing centre. If your amniotic sac hasn't broken before this, it may now.
You may be restless and excited, and you may feel the need to shift positions often. This is good because it improves your circulation.
As your contractions get stronger:
You may want to use comfort measures, such as breathing techniques or massage, to control pain and anxiety. Or you may want medicine for pain, such as epidural anesthesia (Figure 3) . You may be given intravenous (I.V.) Transition Transition is the end of active labour. As the baby moves down, contractions become more intense and longer and come even closer together. Delivery isn't far off.
During transition, you may be self-absorbed, focused on what your body is doing. You may want others nearby for support but be annoyed or distracted by their attempts to help. You may feel more and more anxious, nauseated, exhausted, or fearful.
If you're delivering for the first time, transition may take up to 3 hours. If you've had a vaginal birth before, it will usually take no more than an hour. Some people have a very short and intense transition.

As labour nears, the fetus's head drops down into the pelvis and pushes against the cervix. The cervix begins to thin (efface), sometimes over a few weeks.
Dilation (opening) slide 2 of 2

At the same time, the cervix also begins to open (dilate).

Figure 3 - Spinal and epidural placement for childbirth An epidural usually involves putting a sterile guide needle and a small tube (epidural catheter) into the space around the spinal cord. (This is called the epidural space.) The catheter is placed at or below the waist.
The needle is inserted and removed, while the catheter stays in place. The catheter is taped in place up the centre of your back and at the top of your shoulder.
Medicine is injected into the catheter to numb your belly and lower body. This will help relieve pain during labour and birth.
The medicine for a spinal is injected in a single dose into the fluid around the spinal cord. The benefit of a spinal is that it works quickly.
