diagnosed with a short cervical length at 26 weeks....

Autumn
Got diagnosed with a very short cervical length...😕 apparently normal cervical length is anywhere between 3 to 5 cm and mine is measuring 1 to 1.5. I got put on a pseudo bed rest and just told to take it easy. 
They did the protein swabs and it came back negative thankfully so I should be in the clear for the next two weeks. Has anybody else experienced this and is there any hope of going full-term.?
