having a preemie

We
I had my son 7 weeks early my water broke, my question is other moms on here have there first baby be a preemie and then with there second child being able to carry them to full term? I'm not pregnant again or want to be yet my baby boy is only 9months. My Doctor did say to let her know once I'm ready and I will be monitored more. I hope I can carry to full term once I'm ready for a second baby. Being in the NICU is tough. Any moms out there that have gone through something similar can you share your experience?
