first time preemie mom

We
Anyone on here have there second baby be a preemie? My son was born at 32weeks5days I'm in no rush to have another one, my son is now 9months. I am worried though that what if my second is a preemie also. I've even had dreams about it and it scares/worries me. I didn't have any symptoms of preterm labor my water just broke and he was born the next day. Any mommies who would share there story with me? Well I be considered high risk the second time around?
