While you are pregnant, a plug of mucus is present in your cervix. Just before labour starts, or in early labour, the plug comes away and you may pass this. This small amount of sticky, jelly-like (sometimes pink or bloodstained) mucus is called a show.
The show can come away in one piece, or in several smaller sections. It is normal to lose a small amount of blood mixed with mucus and as a result it is pink in colour. If you are losing more blood that is bright red and fresh, it may be a sign that something is wong, so telephone the hospital straight away.
After you have experienced the show, labour could come quickly or it may take a few days. Some woemn do not experience the show at all.
