Toddler scared of potty

Br

Im potty training my 2.5 year old starting today, doing the whole no diaper or pants thing. She’s been holding it basically all day, she went once on the potty this morning after saying it was too hard and getting upset. But now she hasn’t gone since. She keeps saying she doesn’t have to go and I ask her every 30-60 min to be sure. Does this phase pass? I know she’s ready to do it I just think she’s nervous. What’s the best way to go?
