Danni,
Your fine a cervix shortens obviously with the weight off bubs pressing down and eventually starting to dilate.
Cervix length starts at about 5cm and then as the pregnacy progresses and shortens to dilation during contractions.
When I had my stitch in they said not to worry about the length of the cervix after 30 weeks it is really only an issue 16-28 weeks. So to answer your question you are doing fantastic now turn you little monkey
Not long now
