That sounds like my own daughter too. For the last month we've been on full potty mode! We've been trying since she was 28mos mind you....

Two weeks ago we decided that since she was doing so well with the peeing that we could go to playgroup with just undies on and she actually came to tell me she had to go pee 2x's! She stopped playing with 20+ kids and told me....I was in awe!

Well then she ate oranges (she can't have them....they constipate her) and because it was so hard for her to go poop it messed it all up again. She was going 6-7 times a day but only a pebble at a time.

So now shes not even wanting to go pee as her memory was of it being painful. I feel like we're back at square one again.
