Pregnancy length

So my first was born 37 weeks on the day... Doctor said my second would come sooner, however I had to be induced at 42 weeks with my second because my body was not showing any signs on labor. Now with my third I'm not wanting to be induced again lol anybody else gone thru this? I was really hoping that it was true "the more you have the earlier they come" I'm stressing lol
