birth tips pls ☝️👶🏻

So I'm 5 in a half months now and I'm getting close to my third trimester . So that means I'm getting close to the big day!!!! I'm really nervous only because I am very sensitive to pain . And this is my first pregnancy and I'm high risk. Do you guys have any tips for a first timer here ? I've been watching videos and tbh I know it's going to hurt but maybe there are tips that can help a nervous girl out ? lol I'm suggesting to go to birth classes and parenting classes . Are they worth it ? Thanks guys!
