Anyone with previous premmies feeling anxious coming up to that gestation?

So I'm 30 weeks now and have slowly had creeping anxiety as I get closer to the 33 week mark when I had my daughter/first born. I'm so scared on having another premmie and know once I pass 33 weeks it will ease down my anxiety but it's still constantly on my mind that I could have bub at any time now. My daughter's birth and 2 months in hospital were very very traumatic and i do t ever want to go through it again. Guess I'm just venting as well as wondering how other mums who have been through similar feel/over come these feelings and emotions
