Looking at your Due Date

 

Your pregnancy is calculated based on the first day of your last menstruation (say what??!) were you pregnant on that day? No one knows for sure. Because that first day of your menstruation could have been a real menstruation or an in nestlings bleeding. This gives you already a brother perspective, doesn’t it? It can be that you’ve been already pregnant on that “first menstruation day” for who knows how long…. Might be a week, two weeks even when we look at the most fertile period for a woman, usually 2 weeks after her menstruation. Or, you have been really menstruating and became pregnant two or three weeks after…..  So in this broad perspective there are approximate 30 – 35 days of certainty when your baby will be born.

Having said this, there is something really amazing that you should know.

It’s actually your baby that knows when he or she is ready.
This small intelligent creature inside your womb is the only one that knows.

Complex hormonal communication between your body and your baby signal the start of labor.

When your baby is ready to be born, he or she will secrete a hormone called CRH (cortico-releasing hormone) which sends a chemical signal to your placenta. When your placenta receives the chemical signal from baby, it will release estrogen and cortisol, two hormones that will help your baby’s lung’s mature. Now that the placenta is producing more estrogen, that chemical signal tells your uterus to create more oxytocin receptor sites within the uterine muscle which means you’ll likely have more Braxton Hicks contractions. The increased estrogen production by your placenta also promotes the release of prostaglandins by the amniotic membranes.

 

That chemical communication starts weeks before labor and intensifies in the days and hours before active labor begins.

 

Prostaglandin is a hormone that produces enzymes that will digest the collagen in the cervix, turning it to water, causing the cervix to soften and become thin. In late pregnancy, the placental membranes normally become increasingly fragile, porous and permeable, which means larger molecules from mother’s bloodstream like iron and maternal antibodies can finally cross the placenta, which means baby will gain important immunities from you and about six months worth of iron. Your ovaries will secrete relaxin, a helpful hormone that relaxes all of your ligaments and cartilage during pregnancy, making your pelvic joints wider and more mobile.  That’s especially important in late pregnancy because your baby is descending and engaging in your pelvis, trying to find the best, most efficient position for birth.

The placenta begins making connexin, a hormone that helps the uterus contract in an efficient, coordinated way.  These hormonal reactions will likely cause you to have a restless backache before you have synchronized, progressing contractions which eventually cause your cervix to open. All of these chemical reactions and coordinated release of hormones take time.  Your patience is well worth it:  You’ll have the best chances at the healthiest baby and the smoothest labor if you wait for labor to begin on its own.

 

This is why in HypnoBirthing we prefer to avoid speaking about a due date.
