Its just like an internal, the MW inserted a finger whilst putting a bit of pressure on my bump (but it didnt hurt). She then examined the cervix, as Ive had before, then there was a feeling of pressure as she seemed to push in a little deeper, wasnt the most comfortable thing Ive ever had, but it was totally bareable, but what she was doing was pushing her finger in the cervix and sweeping round in a circular motion. It helps to separate the membrane from the cervix which is supposed to then help the contractions kick in. They dont use a speculum or anything, it is a little uncomfortable but lasts only 30 seconds maybe.
