Ugh, that is just so gross!
I agree that she is not ready. Your idea of waiting another month, is good. I would also go back to diapers and do whatever you have to, to make sure she can't get them off!
~My only advice is to wait till she wakes up from her naps or in the morning dry more times than not. That is what I did and all 3 (2 boys, 1 girl) of my kids were completely (night & day) trained at or around 2y/o, it is a good indicator of where their bladder capacity is. When you do try it again, you really do have to watch her every minute...the success of potty training is really more on the parents part than the childs', IMO. We are the ones that have to watch for the cues and make sure the kid makes it to the potty on time! I also bribed the heck out of my kids, Dum-Dum suckers were my go-to bribe, they are the perfect size and my kids all loved suckers! And LOTS of BIG praise, clapping, cheering and high fives all around!
Hang in there. It sounds to me like you have got it under control and have a good game plan! Don't stress, it will happen and she is still fairly young, so you have LOTS of time!
