Doesn't seem to be getting the pooing in the potty

I potty trained my LO over Easter weekend i had a couple of accidents in the first couple of days then she has been dry for 6days no wee accidents. Doesn't have to be prompted will ask to go to the potty. However we only had one successful poo on the potty, some days she held it, another day went overnight in her nappy and today and yesterday she went in her knickers, she will tell you as soon as she had done it but not beforehand and seems really upset about pooing in general in her knickers or in the potty, even the one she did in her nappy she got really upset over. Any tips?? Do I just ride it out and hope it clicks? Or am I going to have to put her back in nappies?
