Feeling nervous.

I’m almost 38 weeks with my second. My first birth was great, I went into labor on my own, had my son at 39+4 with no complications and was able to have the natural, med free birth I wanted. This time around I’m feeling scared shitless! I think it’s because I know what’s coming. And honestly my mind is going to bad situations. Is anyone else on a second (or third, forth etc.) birth and still feeling really nervous?
