Braxton Hicks contractions
Braxton Hicks, also known as 'practice contractions', are 'false' contractions that are often felt from about week 20 during pregnancy. Named after the doctor, John Braxton Hicks, they aren't painful exactly, but are often described as a sort of tightening across the belly. They can take your breath away a bit if you don't know what to expect, but don't be fooled – they're nothing like the contractions of full-blown labour. Look on them as nature's hilarious little prank on first-time mothers.
What are Braxton Hicks?
Braxton Hicks are a type of contraction, but they don't signify the start of labour. Essentially, the muscles of your womb contract – typically for between 30 to 60 seconds at a time, but occasionally for up to two minutes, causing a squeezing feeling across your belly. Sometimes your bump has a funny, 'rigid' look to it as this happens. They usually subside within 20 minutes to an hour.
What do Braxton Hicks feel like?
Most women describe a feeling of a band tightening across their bump. The sensation is mostly high up and at the front, rather than in the pelvis or lower back (like labour contractions). Some women feel nothing at all, but notice that their bump has gone rigid and changed shape slightly. Each one tends to last less than a minute and shouldn't be too uncomfortable. There's no need for pain relief, but as you near your due date, you may find that they become a little more intense.
Some women describe a very mild ache, like light menstrual cramps, but often, the contractions are undetectable.
When do Braxton Hicks contractions start?
Technically, they can start at around week six or week seven of pregnancy but you don't tend to notice them until around the middle of your pregnancy when your uterus is much bigger, in the second to third trimester. Most women who experience them feel them from around week 20 and you'll notice an increase in frequency as your due date nears.
Do Braxton Hicks contractions hurt?
They tend to be just uncomfortable, rather than painful, so don't dash to throw your hospital bag in the car until you're sure. Many a first-time mother has looked back on her Braxton Hicks from the very much more painful throes of second stage labour and laughed at the memory of wondering if 'this could be it'.
While not as painful as true labour, Braxton Hicks are often still not a pleasant feeling (in comparison to a shoulder massage and a box of Ferrero Rocher, say), so you can feel entitled to wince a bit and put your feet up when they occur.
Why do they happen?
Experts are divided as to Braxton Hicks' purpose – some believe they help tone the uterine muscle, promote blood flow to the placenta and increase oxygen levels sent to the baby, others think their purpose is to help soften the cervix in preparation for labour.
Alternatively, it could just be your body having a right royal laugh at your sanity's expense. Braxton Hicks are often known as 'practice contractions', and they're handy preparation for the real thing. You can practise not swearing at your other half when you are doubled over – or practise your breathing exercises without feeling quite so foolish. So they aren't wasted.
How do you tell the difference between Braxton Hicks and real contractions?
Many a red-faced mum-to-be has been turned away from the delivery ward thanks to Braxton Hicks – especially during the latter stages of pregnancy, when they can increase in frequency and strength – what's sometimes referred to as 'false labour'.Braxton Hicks were bump-hardening, pretty painless and made me slightly breathless. Real contractions felt like someone forcing a big nail very slowly into my coccyx.
Typically, Braxton Hicks differ from the real thing in that they're irregular in intensity and frequency and their timing is unpredictable and non-rhythmic – they tend to turn up, do their erratic thing and then taper off. Plus, they're usually not truly painful, just uncomfortable.
In contrast, real contractions last longer, increase in regularity, intensity and length, and get closer together as labour progresses. They also become progressively more painful and don't stop if you change position or do something different (see below).
What can I do to alleviate them?
You can, of course, simply ride them out – but if you want to try to alleviate the feeling, it helps to think about what triggered them.
Common triggers include being active, someone touching your bump, having a full bladder, being dehydrated or having sex (so don't get overly fruity when you need a wee and are gasping for a cuppa). Seriously though: changing what you're doing can often help, particularly if it's one of the following:
- go for a wee
- change positions – get up and walk around, if you've been sat down for a while
- have a couple of glasses of water (particularly helpful with regard to the first point)
- if you've been doing something strenuous, sit down and give yourself a break for a while
- have a soak in a warm bath (but avoid really hot water)
Although they can be a little uncomfortable sometimes, don't panic. The contractions are completely harmless to your baby and nothing to worry about unless they seem to be turning into something else. If you have any concerns, give your midwife a call. They'll be able to advise you and hopefully put your mind at rest.
When should I worry about Braxton Hicks contractions?
Sometimes Braxton Hicks can become stronger and more regular and, if you're 37 weeks or more, it could be one of the early signs of labour.
Warning signs to look out for if you're experiencing contractions include:
- Lower back pain/cramping
- Bloody or watery vaginal discharge
- Regular contractions coming less than 12 minutes apart
- Heaviness in your pelvis and the urge to push
If you're less than 37 weeks pregnant these could be signs you're going into premature labour and you should contact your doctor or midwife immediately.
If you're beyond 37 weeks, the above symptoms could mean D-Day has arrived.
Should you experience any of the above or you think your waters have broken, you're bleeding or you have noticed a change in your baby's movements, you should still also speak to your doctor or midwife immediately, regardless of what else is going on.
Should I worry if I don't get them?
No. Like morning sickness, heartburn and all the other pregnancy aches and pains, not everyone gets them (or at least they don't notice them) and there's no need to worry if you don't. Not experiencing them over the course of your pregnancy won't affect your labour, and it may be that you have had them, but haven't noticed – especially if it's your first pregnancy.
