Potty training 2 year old, what should I do?

S

My 2 year old daughter has basically been potty training herself this past week. She's only been using diapers at night when she sleeps and when we go out. Lately I've been able to get her to use the rest room when we're at someone else's house, she doesn't wet her diaper.

Here's my issue. I've got about 4-5 diapers left, wondering if I should buy more, get pull ups or just buy more panties? What would you do? I don't wanna waste money on diapers if shes doing good but I don't wanna jinx anything. Advice please!
