Short crvix at 28weeks

Hi, I am a FTM 28 weeks and just found out that my cervix is 7mm long. I have been immediately admitted to the hospital, getting steroids, an arabin pessary and progesterone. They mention I should stay at the hospital indefinitely due to the risk of preterm labour at any moment. While I want for the baby to develop as long as possible, I am also getting anxious about the thought of staying in the hospital for weeks. We are still due to buy pretty much everything for the baby and getting the house ready, and I was just starting to look into post-partum. Any similar experiences? I am hoping that at some point I can go home and take it easy there instead.
