Short cervix and very SCARED
This is my third pregnancy and I am almost 27 weeks pregnant I have had to have many ultrasound because of placentia previa well today I had another one and it showed that it is now considered just a low lying placentia which is a relief, but now they found that my cervix is getting shorter.
It measured 3.1 mm and when she put pressure on my abdomen it went down to 2.8 The midwive said that a normal cervix is 4.0
What does this mean and why does it get shorter with pressure?
Thanks
