2nd baby experience?

Mi

I had my daughter at 34wks, she was in the NICU for 14days. She’s now 2.5yrs, and we want to TTC next year. My doctor already told me I’ll see a high risk dr and will have to get the p17 shots. Those who had a preemie and then had another baby, was your 2nd also a preemie? If not, did the shots help and how much further did you make it? I’m very anxious about another preemie and Nicu experience... anything you want to share would be helpful
