Potty training troubles

Hello need help potty training any advice will help at this point. Daughteris 4 she just started finally talking after speech therapy and we wanted to start trying. I use to take her to the toilet (whether in the big or lil potty) every 15 mins and give her a sticker wen she would at least sit. Did this for couple days with no actual pee or poo happening. Now shes starting to resist even going to sit. Im scared and dont wanna drag her to the bathroom. I dont wanna scare her from using it. Any advice would be amazing.
