Currently 36 weeks and worried

Hi mummies, i’m currently 36 weeks and 6 days, I’m already feeling tightening and pelvic pain. I gave birth to my first one exactly at 39 weeks going 40. Found out on the internet that i’m only on full preterm and i should be more cautious, but should i have any worries if i were to give birth early of 37 weeks? Will there be any possible risks that i need to be aware of if i were to be giving birth anytime soon? Feeling very anxious and worried 🥲
