1 cm dilated!

Shonise • I'm 25 years old. I have a 3yr old daughter and a 9yr old son. I'm happily engaged as well! Nd now pregnant with my 3rd!
OK so when I went for my check up two wks ago which I was 32+5 I was 1 cm dilated so my ob she put me on bed rest until I turn 34 weeks which is tomorrow!(new years <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a>) And stated if I have my son @34weeks or afterwards everything would be find. OK I get that. But I really hope I don't dilate anymore until at 36 weeks then I'll know I reach the last stage(9months) so how long you guys think if I'm already 1 cm dilated I will go into active labor??, because I DONT want to go in labor no time soon, at least if I go in at 36 weeks then I'll feel much better better.
