TTC after preterm labor

Hi everyone! 7 years ago, I had my daughter at 31 weeks after an otherwise completely normal pregnancy. We spent exactly 1 month in the NICU and have been lucky enough that's she's only had minor lung issues over the years. My SO and I have just started TTC and after all these years, I'm still terrified that we'll once again end up in the hospital. I'm mostly afraid of time management with a 7yo at home and a baby in the hospital (which is 1.5 hours away).

What are your experiences with pregnancy after preterm birth (specifically preterm labor with no known cause)?
