Potty training

So I’ve been potty training my daughter for about a week and a half now and it’s been going great..she tells me when she needs to go make potty and everything no problem.But one big problem she has is she won’t say when she needs to go make number 2 and will just go in her underwear ..but with peeing she’ll head right to the potty.How do I get her to go to the potty and make number 2 without her going in her pants
