Short cervix

Milena

I was having pressure in my uterus today so I went to the baby center and they monitored me for 20 minutes. I though they might be Braxton Hicks but she said she didn’t see that but she wanted to an exam. I’m 27 weeks and she said she did notice that my cervix is a little shorter then she would like. So she asked me to come back tomorrow to be monitored again. Anyone have an experience with this ?
