worrying about labour already

Cherokee
I'm only 12 weeks and I'm already worrying about the labour. My first pregnancy Was with twins and had it vary easy, no labour pains what so ever. I had a c-section and it went smoothly even afterwards I didn't feel pain from the c-section so it was actually pretty easy of a pregnancy. But this pregnancy it's already vary different I feel everything even the littlest things like pains in the back, to tender breasts, it's already vary different and I'm scared for the end of this pregnancy.
