Sexual identity ?

So basically I’m a female who has only strictly dated guys but recently I find myself attracted to girls too however I don’t know if I’m bi. I’m still coming to terms with whether or not I like girls because I don’t want to come off as being a fraud which sounds dumb. I have a girl coworker and her and I just joke and laugh all the time but I think we’re just being friendly. About a month ago she asked if I had a boyfriend and then if I had a girlfriend but I said no and maybe less than a week ago she asked if I liked girls and I told her “a little bit” because I’m confused as to whether I should label myself or not. But anyways since I told her that I liked girls a little bit I look at her different and I have a crush on her and if she turns out to like girls too I could honestly see us dating. Again I’m just confused on if I should label what I am right now or not and if I do label myself would it be bi, pan? I’m not sure.
