Hi mummies, wanna ask to those who have experienced giving birth to premature bb... Is it safe for me to give birth at 35 weeks or either 37 week as I'm having contration n in bad pain??

I had my son @35 weeks he weight was 7 lbs but I’m dietetic so we tend to have bigger baby’s was in nicu for ten day just to stabilize sugars because of me no him now pregnant and will have this one at 37 weeks due to me being dietetic
