Could still even be a few weeks yet. At 36 weeks I was 1-2 cm and 50%...at 38 weeks I was 2-3 cm and 50%...had my kid at 39 weeks. No way to know for sure.
I was 3cm dilated & 80% effaced from 26 weeks on. I ended up having my daughter at 42 weeks so unfortunately I don't think things will move fast just because you're dilated already.
I was 2cm dilated for two weeks, and still had too be induced with my son. But every one is different.. but congratulations!! Your Almast there
