I kind of agree with you in that you decided she wasn't ready. Because you were waking and toileting her, so she wasn't independently going overnight etc.
I guess you can go back to doing that, but it is winter!
You could stay with a pull up and make sure it is absolutely the last thing before bed (I.e. not sitting on the couch) and it comes off straight away in the morning.
Could you leave her in a pull-up and start doing rewards for dry nappy? If that's enough to encourage her not to wee in it when she is awake and aware. Then if its still wet, you know it's because she is still weeing while she's fast asleep.

I'm not sure about rewards for night dryness. If they aren't aware of their night time wetting, then it seems kind of unfair. But if you think she is being lazy or head strong, then it might work.
