Preterm questions

Eloen
I went into the hospital yesterday for back pains and was told I was j. Preterm labor. I will be 26 weeks Monday. I dilated 1cm. They test to see if my water broke and it came back positive but could be due to me having sex two days ago. So the sent me home and told me to stay in bed rest and I'll come back Monday to re-test me. Does this mean I could have my baby early and if so how early.
