Ready to try again but...

My husband wants a another baby after I was admitted to the hospital at 27 weeks and stalled out and was there for a week n had the baby at 28 weeks which he is perfectly healthy at 14 months but the doctors told me I would be high risk my second pregnancy which I would get a shot to keep my body from giving up early n monitored but im scared to get pregnant again because of the experience I had with my first pregnancy...
