Membrane sweep: Everything you need to know

Membrane sweep
Membrane sweep is not the most pleasant of pregnancy experiences, but if you've been wondering what it is, then you've come to the right place! It might seem scary at first but you may well be feeling differently by the time your due date has been and gone and you're struggling to even get to the toilet!

This guide will tell you all you need to know about membrane sweeps, and hopefully dispel any horrible myths you may have heard about them, too!

What is a membrane sweep?

Its full name is a membrane sweep and your midwife will suggest it as the first option when you're overdue, i.e. once you're more than 40 weeks pregnant. What happens, simply, is that your midwife or doctor will ask you to lie down with your feet together and your knees to each side. When you're as comfortable as you can be they will then insert a finger inside you and pass it around your cervix. This will slightly separate the membranes of the amniotic sac surrounding the baby from your cervix and release hormones that will hopefully kick-start your labour.

We won't lie, it can hurt and you'll be told to try to relax and breathe deeply as they work their finger around. Janet Fyle, midwife advisor for the Royal College of Midwifery says, 'the sweep, which is simply a regular internal examination, often wakes up the cervix to do its job and progress the woman into labour. It can be uncomfortable and painful, but labour does become more likely after a sweep and so reduces the need for being induced.'

Sometimes your midwife or doctor will suggest you will need a 'Stretch and Sweep'. This means you're not quite ready for a membrane sweep so instead the midwife will stretch and massage your cervix. This may begin the 'ripening' of your cervix so your next appointment with the midwife will be for a full-on sweep.

Although you don't need to prepare yourself for a sweep, you may want to gear yourself up a little for a few minutes of pain. Just like having an injection, you're not going to enjoy the experience, but just think, it will bring you closer to meeting your little one! Also, it might be an idea to wear a pantyliner or maternity towel, just in case of any spotting after the sweep, many women choose to wear one by this stage in their pregnancy anyway.

When would I need a membrane sweep?

When you've reached 40 weeks after your last period you're considered full-term. It's not good for you or your baby to go too long after this date to give birth. If you're a first-time mum you'll most likely be offered a sweep at your 40-week antenatal appointment with the midwife, and again at 41 weeks.

If you've already had a baby, you'll be offered a sweep at 41 weeks. Sweeps are your first option before the midwife suggests inducing your labour. It means your body kick-starts labour itself and so you release the right levels of hormones for your body's labour to begin. It's thought that an induced labour can be more painful than a naturally begun one because the hormone levels are set by a doctor. Most mums find the labour an induction brings on is more intense and painful. Sweeps are not without pain, unfortunately, and you can end up having 2 or 3 before labour starts or before an induction is suggested.

Remember, just in the same way as you can ask for a sweep, you can also say no if you'd rather wait and see if nature takes its course. If you do decide to wait, the midwives will be keen to keep an eye on your progress every day that you go beyond your due date.

What can I expect to happen after a membrane sweep?

'We tell women to carry on as normal after their sweep but they must keep an eye out for any changes. There can be a little blood, it can also bring on the 'show' and, of course, it will hopefully make labour happen,' says Janet Fyle.

What other mums thought:

'I was dubious over whether a sweep would work or not but I went
in for the procedure, went on with my day and few hours later I was in
labour, a quick one and in less than 24 hours I had my baby girl.'
Jo B

'I had 2 or 3 sweeps with my first baby and it was useless. A very unpleasant experience too. Some say it works but you never know if the baby was just ready.' Lorna C

Im 40 +3 and I had a sweep done today at 5:30pm came home and i cramped for an hour and my stomach got really hard. I wasnt sure if i should call the dr bc it went away after an hour. So its 10:25 pm and i dont feel anything. Maybe she will be here tomorrow i hope this sweep helps!


I had my membrane sweep on Friday 28th july, day after my due date. Took two midwives as one was a student. Wasn't pleasant! I was 1cm, so it was just s sweep rather then stretching. I had cramping and felt like I was having a bad period and felt really low for the rest of the day. Had a curry that night, had spots of bleeding. Saturday small cramping and slight discharge, then Sunday no cramping and no discharge. Today Monday 31st july no cramping but having a lot of jelly discharge. Going swimming tonight. Tomorrow I have my midwife giving me another sweep, which I am very skeptical about it working this time.

I had a sweep yesterday afternoon after40weeks and 4 days. It hurts real bad . This is my first baby. I had light bleeding afterwards, bloody shows, and irregular contractions which had stopped within 3 hours. I'm still very pregnant . I am schelduled to be induce tommorow morni.


I had a sweep 2 days ago (on my due date). Turns out I was already 4cm dilated so it didn't hurt at all, in fact I was pleasantly surprised at how fine and comfortable the experience was. I had light bleeding afterwards, bloody shows, and irregular contractions which had stopped within 12 hours. I'm still very pregnant (annoyingly) and uncomfortable as baby is back to back. My midwife is coming again tomorrow to do another sweep. I'm feeling far more relaxed about it, and hopefully my cervix has moved into a more anterior position as although it was dilated, it was still quite posterior. For anyone worried about the pain of a sweep, I think it just depends on how "favourable" your cervix is at the time. You can always change your mind about having it done!


I had my sweep just yesterday and I'm due today. I have alot of cramping and this is my second pregnancy so I don't know what to expect because they didn't do this when I was pregnant with my son 4 years ago


I've had three membrane sweep in less than two weeks, I'm scheduled for an induction tomorrow, it has t started labor but it has got me from 1 1/2 cm to 4 in less than a week


Had my sweep at 38+3 weeks on a friday 11am,soo painful the procedure,had regular contractions for an hour and then irregular with pain quite down low, all day,with pelvic pain,period pain,back ache pain,feeling sick,diharoea,realy painful to walk,my belly feels rock hard .Saturday morning had my mucus jelly plug come out with more similar reapeted day like Friday,slightly more intense contractions,but faded later around 9pm,and was able to rest after such exausted days.Sunday morning feeling awfull and hoping not to have a day like Fri/ girl still here..Rang the hospital few times to tell them about some changes but they said i should coming when my contractions become every 5min with a minute apart..Im so confused/worried when is the right time to go to be checked at least.This is my second child with 15yrs apart,and was induced with my first..i am a bit cluless with the natural course of labour..Anyone experienced this??!!
