Short Cervix

Catherine

Anyone have a short cervix? I was told by doctor after ultrasound I am 1.2cm... cant get an appointment until next week for specialist. Not sure if i should go to ER or wait. I dont have severe pain or bleeding, but cant walk outside very much without some pain, so ive been in bed. Whats signs should i look out for to go to the ER, i def dont wanna loose my baby at 20 weeks :(
