Potty training help!

Not pregnancy/period related. My lg is 2 - 3 in June - and for the past maybe month we've been potty training at home during the day, we went a week ish in nappies again because she got ill and wouldn't go near the potty. Anyway, she's done really well.. Knows when she needs to wee, wears knickers & knows to take them off before she wees, hasn't had an accident for a while (apart from a poo yesterday 😷 yuck lol) but I'm so scared about taking her out in public with pants. We're not planning any big trips yet, but we live just down the road from the park so we can walk up there as her first time out without a nappy. I'm just after some advice and tips from experience? Just the thought of going out is giving me anxiety!
