Don’t know if I’m straight or bi??

Okay so when I was a little girl, I was best friend with my neighbour who was a girl but at some point we started to kiss but we were too young and it didn’t mean anything. Now I’m a teenager and I used to have a boyfriend but I Dk what I feel anymore? I thought I was straight but I’m unsure now. Sometimes I find boys attractive but other times not and with girls some of them are attractive but I don’t know. I wrote this cause I need advice on what to do cause I don’t know what I feel anymore.
