Glad things are staying the same! I agree with others that posted. I was in the exact same place as you guys are at. my cervix got dramatically shorter at 22 weeks, they put me in the hospital and gave me steroid shots as soon as I made it to 24. Though my cervix quickly went below 1cm (and eventually was paper thin) it never gave out. I delivered at 33 weeks 3 days due to pre-eclampsia not because of my cervix. I was very strict about bedrest the whole time in the hospital. I stayed on my left side and drank lots of water. I also took procardia medication in case it was pre-term labor shortening the cervix(I was having mild contracting). Oh and I talked the doctor into giving me progesterone shots even though it wasn't proven to help with a multiple pregnancy. I told the doctor i wanted to try everything possible! It may not have helped but I felt better doing everything I could. At least in the hospital they can monitor you and potentially do something to stop labor if labor starts. I will be praying for your family!
