It sounds like she may be "in control" of knowing when something is coming, but is a little fearful of it. This can happens for lots of reasons that are impossible for me to know sitting on the other side of the computer screen, and may be difficult for you to figure out - including uncomfortably large or hard poops that have caused her to try to hold it to more psychological reasons that would require the help of a professional (and lots of things in-between).

Have you asked her about it when she is not headed for the potty (or messy)? Something like, "honey, is there a reason you know that makes you not put your poo poo in the potty?" You might have to try a few times, but, if asked in a calm, casual way and given time to think about and formulate an answer - she might surprise you with a clear answer.

If you think her poops might be uncomfortably large/hard for her and some constipation may be an issue - check with your pediatrician about dietary changes and stool softeners to help ease things along.

For some children, a fear of the toilet flushing what they see as a part of themselves away can become an issue. If you think this may be the case, it is healthy to talk about her poops as "presents for the potty." When she has accidents, make sure she sees you put the poop in the potty, say "bye bye poo poo" and "your welcome potty" and make a game or ritual out of flushing the poop. After a little time has passed, you may find she might start a "more direct approach" to offering up her poop to the potty.

It is a different set of signals for the brain, and although there is more time between feeling the "need to go" and the actual "going" especially for a child that wants to be moving and playing sitting and waiting long enough is pretty hard. If you do decide to keep at it, I suggest sticking pretty close to home for awhile and spending every hour to hour and a half in the bathroom (with her on the potty) reading books and singing songs for ten to fifteen minutes. Try to make the bathroom a fun place to be so that "wait" doesn't seem like a loss in play time and a big old bore.

It is also possible that she isn't quite ready yet. For some reason, using the potty for poop is harder for some kids than using it for pee. You could take a break for awhile. Many people warn strongly against this. With kids that are completely ready and are in the middle of things but training just becomes inconvenient stopping in the middle can make things more complicated. However, you're already stalled and she may be mostly there, just not quite, so it isn't likely to make things worse to take a little break - as long as she knows the break isn't happening because of her. I'd suggest asking her what she thinks to insure you don't create the situation where in her mind, the break happened because she failed. "Hey, do you want to keep trying with putting your poo poo's in the potty for awhile, or would you like to take a little break and try again in a couple of months?" She may have an opinion on the matter.

Kids are training a little later than they used to these days, so You are probably fine, if by the time she is 3.5 yrs, she still isn't using the potty for both, definitely ask a pediatrician about it so that if it is one of those other more serious reasons that can be dealt with. In all likelihood things will work themselves out before then though. Good luck.
