This is when your body works to open up your cervix so that your baby can come out. This happens when your uterus presses down on your baby, whose head then presses down on your cervix. This, and the release of the hormone oxytocin, will trigger contractions. Contractions will probably feel like physical discomfort, dull ache, and pressure in your pelvis, back, and lower abdomen.
A lot of women compare them to strong period cramps. The phase when your cervix dilates from zero to six centimetres is called early labour and it can last for quite a long time, as long as hours or even days.
During early labour, your contractions will be mild and irregular at first and then progressively become more intense and frequent. Active labour will generally last between four to eight hours. Together, these two phases make up stage 1 of labour. Stage 2 of labour will be when you actually deliver your baby, which includes all of that pushing you hear so much about.
After that, your uterus will immediately continue to contract in order to get back to its normal size. Learn more: Postpartum - A survival guide for the fourth semester.
Just like with every part of pregnancy, there are a lot of hormones at play in the labour process. First up: oxytocin, which is often known as the cuddle hormone, as it is released when people snuggle up or bond. Oxytocin also plays a role in labour, as it triggers contractions and also the letdown of your breast milk.
All of the loosening of your cervix, joints, and bowels that comes along with labour is caused by the hormone relaxin, which does exactly what it sounds like. Another hormone, prostaglandin, also helps to open up your cervix, as well as allows your body to be more receptive to oxytocin. Finally, your body will also release epinephrine and norepinephrine, also called adrenaline and noradrenaline, which you might know as the fight-or-flight hormones.
Having a cervical check at the end of pregnancy is a personal decision, but if you want one, Dr. Berghella says to ask your doctor about it in light of this new evidence. But why exactly is the onset of labor such a mystery to begin with?
A second study published in the journal PLOS One may help illuminate how the body knows when to start the delivery process. Researchers at The University of Texas Medical Branch discovered certain cell markers that happen as a woman starts labor. They found that changes in telomeres, part of our DNA that responds to aging, become present in the amniotic fluid as the placenta and other pregnancy tissues get older.
These cells could be telling the baby that it's time to be born. Saade, M. So we assumed that if the baby is to send a signal to the mother that it is in trouble and needs to come out, the telomeres would be good candidates.
Because this natural aging process, or "senescense," happens all the time in our bodies, it's possible it could also be connected to the pre-labor changes in the cervix that transvaginal ultrasounds are detecting.
The same processes we found may also be occurring in the cervix," Menon and Dr. A certified nurse midwife weighs in on natural tactics that women use hoping to coax their bodies into labor.

What Parents Need to Know. Truth or Tale? In a study , women who had recently delivered babies were surveyed about inducing labor at home.
Of these women, 50 percent had tried a natural method of getting labor started. Exercise can be anything that gets the heart rate up, such as a long walk. Theoretically, there are multiple reasons why having sex could induce labor. For example, sexual activity, especially having an orgasm, can release oxytocin, which may help jumpstart uterine contractions.
Also, for pregnant people who have sex with men, there are prostaglandin hormones in semen that might help ripen the cervix. Doing so can increase your risk for infection.
Stimulating your nipples can cause your uterus to contract and may bring about labor. Nipple stimulations stimulate oxytocin production. Oxytocin is the hormone that causes the uterus to contract and the breast to eject milk. In fact, if you choose to breastfeed your baby right after delivery, this same stimulation is what will help your uterus shrink back to its original size. You or your partner may manually stimulate your nipples, or you can try using a breast pump.
