Preterm labor

Hey ladies! It's the chick with the stupid med problems again:) as I've said before, I'm 19, my average pre- pregnancy weight was 74lbs. I have a genetic bone disease that makes me naturally petite. Because of this I have to deliver via csection between 34&36 weeks. So early December. My OB specialist said that because of my bone disease, my uterus being so small can speed up the birthing process for the baby so I have to be prepared at any point from now to December. How do I prepare..? My house is getting condemned by the county which means we have a month to find a new place to live. I have most necessities that my son will need, but how am I supposed to be prepared for likely preterm labor when I'm not even capable of giving vaginal birth and could not make it to the hospital in time. Idk I'm worrying myself, I know that. I just can't help it😢
