The mucus plug – one of those gross things you take a crash course in when pregnant. Let’s talk about this little wonder of pregnancy and what to do if you lose yours early or if you don’t lose it at all!
A mucus plug is literally a plug of mucus that fills the cervix to protect your baby from bacteria and disease during pregnancy. The “firm jelly” substance accumulates during pregnancy and blocks the cervix up until the cervix softens and dilates at the end of pregnancy. In the lead up to child birth, some or all of the plug may be discharged.
What is a mucus plug made from?
Similar to nasal mucus (aka snot) the mucus plug is a moist ‘blanket” protecting your growing baby from bacteria. It contains enzymes, proteins, cells and antibodies all with a single mission – to keep germs away from your bub.
I lost my mucus plug early – is this bad?
Firstly, you can lose ‘bits” of your mucus plug while the plug remains intact. So while you may be worried that you’ve lost your plug early, it might just be a small portion of it. This is usually nothing to be concerned about. Let’s face it, there’s nothing as weird and unpredictable as a pregnant body!
However, there are two concerns around early mucus plug ejection. The first is that the baby loses protection from bacteria and viruses. As mucus plugs can be lost any time in the last ten weeks of pregnancy, it’s pretty common for a baby to grow “plug free” for the last trimester however, your birth team may wish to discuss this with you.
The other issue is that losing your mucus plug is a sign that your cervix has started to soften and dilate in preparation for birth. This isn’t always an issue and you should discuss it with your birth team. It can however be a sign of an “incompetent cervix” – which means your cervix is struggling to keep the baby in place. If in doubt, always discuss concerns with your birth team. There’s every possibility that early loss of a mucus plug is nothing to be concerned about at all.
Wait, it can my mucus plug grow back?
Your mucus plug can be “accidentally” dislodged. Sex and other “physical activities” as well as infections and plain bad luck can mean your mucus plug evacuates early. Don’t panic. Because the mucus plug accumulates throughout your pregnancy, it may just ‘grow back’ – but with all things a bit “unusual” it’s best to talk to your birth team if you do lose your plug early.
What does the mucus plug look like?
The mucus plug is cloudy in colour, has a thick “gelatinous” texture and is sticky. As you get closer to delivery day, it may be stained with a little blood giving it a redish tone. But every pregnancy is unique so there’s not one rule for exactly how it will look. If you find that there’s a “blob” in your underwear or toilet, it’s probably your mucus plug or part of it. It can look like a long strip of “snot” (imagine the biggest nose blow ever!) or be more rounded and plug like.
The most frequently asked questions about how your mucus plug looks? Here’s the answers:
- Yes, a mucus plug can be brown
- A cervical mucus plug can also be completely clear
- Yes, you can lose a mucus plug slowly, so it may come in several pieces over several weks
- Losing your mucus plug can come with a bloody show
- Losing your mucus plug can come with no blood at all
- How much mucus plug depends on your body, but is usually a few tablespoons
We asked our community about how their mucus plug looked:
- My mucus plug was very clear and extremely sticky. Couldn’t wipe it away. Had to pull it out. Lasted for about 2 days and the last thing to come out was something that looked like a 3-4cm dried piece of silicone. Everyone told me it would be tinged with blood but there wasn’t a speck of it. It was a lot like clear snot haha Anon
- My mucus plug came out continually over several days – little mucusy streaky strips. Phoebe
- Mine was a bloody show as they say. It was brownish coloured and tinged with streaks of blood. Simone

Community question: I’m wondering how long after losing my mucus plug will labour start. I am 37 weeks on Sunday and started I am losing mucus plug last night and again this morning. After seeing the doctor today he thinks bub will be arriving in the next week, how long after losing your mucus plug did you go into labour?
More than a week after losing plug before labour
