I’m 36 weeks and 3 days and my doctor checked me today and I was 1cm dilated and 50% effaced but I’m also having some cramping in my pelvis area but that’s all I believe is normal also having painless contractions (which are now doing something lol) but i don’t think it’s anything now

my question is,

is it okay to be 1cm and 50% effaced at 36 weeks? How quickly can it change? I will be induced at 39 weeks and hoping to just go naturally.
