Re: Not doing it "right"
I think you might be at the point where you need to "reset". That's where you go back to diapers for 2 weeks, pick a new PT start date, and just have a do-over.
The "Oh, crap! Potty Training" book details how to do this. Start today, put her back in diapers, then read the book.
(I do not benefit from the sale of this book. I hope you will though.)
