Potty training

Not gonna lie I am clueless to this. We have had a potty for a while but she’s not shown interest until the last few weeks. We took her to pick her own underwear, bought her a no more nappies story book and sticker chart. Yesterday was the day we thought let’s see how it goes. I was working so my partner was responsible & kept asking if she needed to go and she said no although did sit on the potty a couple of times. Whilst he was getting dressed she stayed with me but like I said I was working so not fully concentrating and I noticed she’s gone quiet but she’d already poo’d at this point and was upset about it. We told her it was okay and just cleaned her up. Today she had ballet class so needed a nappy. We took it off at home and kept asking if she needed a wee but she said no, she went about 5 hours of us asking without having a wee then she did have an accident which again she was very upset about 🥺 10 mins later she poo’d and was very sad again. Do I persevere or is this a sign she’s not ready? Wondering if I’m trying too early and I don’t wanna give up to early but then also don’t wanna keep persisting if she’s not ready for it and cause her any distress. This is so hard. Any advice pls ??
