Finally got my 22 month old in her cot, when should I move her to her own room?

As tittle says;
I’ve been in a constant battle with bedtimes with my little girl (22 months) since she was 3 weeks old. We co slept in the end and kept trying to put her in her noses/next to me/cot throughout this time, but she’d have absolutely none of it. So cosleeping was all she knew (it was the same for naps too)
Well suddenly, she’s decided she wants to sleep in her cot! AT LONG LAST!! The last 3 nights she’s been in there only once waking up if she’s lost her blanket and can’t wrap it around her legs.

I’m just trying to decide when and what is the next step. When to move her to her own bedroom next door to mine! Should I leave it a week to see how she goes and see if the one night waking stops?

I am in a slight rush, I am 31 weeks pregnant with a slight likelihood this baby will come a bit early like my little girl did.
