Pregnancy-what is a show?

Show FAQs

What is a show?

A show is the mucous plug that functions as a sealer for your cervix during your pregnancy. It helps protect your baby (along with the amniotic sac) from the external world and it stays with you until you are ready for delivery.

What does losing the mucous show mean?

This is a sign that your cervix is going through the labour process, softening and dilating, preparing your uterus and body for childbirth.

What does a mucous show looks like?

Imagine a cork, but clear, gelatinous and with a mucous texture.

Should I pull out my own mucous show?

No, you should never do that. By doing this, your risk of infection will get very high. We know that pregnancy can make some women anxious, but let nature do its work.

How long does it take going into labour after losing the mucous show?

This varies from woman to woman. This period of time can go from a few minutes to a few weeks before the labour process starts.

Is something bad going to happen if I lose the mucous show early?

You do not have to worry about it, nothing bad is going to happen. It does not matter if you discharge your mucous plug weeks before labour, your baby is still going to be protected by the amniotic sac and new developing mucous. You can have a normal pregnant life until labour starts.

Will the mucous show always discharge?

Yes, this mucous cork will always discharge before labour. A different thing is that some women may not notice this process (for many reasons), but it will always happen.

Will my water break before or after losing the show?

Commonly, this happens before, but you can sometimes leak amniotic fluid due to a tear in the amniotic sac. Either way, if your water breaks or you begin to leak fluid, you should go to your doctor.

What is a bloody show?

A bloody show is the same as a mucous show, but with blood. This occurs because the blood vessels located in the cervix are rupturing due to this structure´s labour changes. This should happen after 37 weeks of pregnancy. If it happens earlier, you should go to your doctor immediately.

How long does it take going into labour after releasing the bloody show?

This can go from a few hours to a day or two. Either way, prepare your bags and go to see your doctor because you will not have that much time until the first labour signs arrive.

What Our Patients Say

Gráinne Macken

This is my second visit to Merrion Fetal, I was very pleased on both occasions. Lovely quiet waiting room, appointment was on time. The 20-week scan is very detailed we enjoyed watching our baby on the large TV screen. We got some beautiful photos. The nurse was very pleasant and talked us through all the measurements and anatomy. I would highly recommend this scanning clinic.”

Áine Gibney

I had the best experience at the Merrion Fetal Health clinic for my 20-week big scan. The staff were so friendly and so nice and the lovely lady who did my ultrasound scan was amazing. She was so thoroughgoing to absolutely everything and gave me such reassurance on how my baby was growing and developing. I would recommend any Mother to be to attend here if you are looking for a comfortable, reassuring and super pleasant experience.”

Linda O'Sullivan

Highly recommend! We had an early scan due to a little scare at the start of pregnancy and then another at 12 weeks to make sure all was good again. Helen who was scanning on both days was fantastic. We felt totally relaxed and un-rushed while she took her time finding the best angle of baby to get us the clearest pictures as keepsakes all while making sure everything was perfect with baby. She reassured us throughout and I can honestly say it was the best money we ever spent getting both scans done.

Please let Helen know we are 18 weeks now and flying along Highly recommend!
