prom and period

Hello everyone, so my prom is on June 9 4 days from now and I'm supposed to get my period, I'm on the pill:) so my doctor said when I first got on the pill that I could just skip my place bos and go straight to my active, so I did that for prom week I was supposed to start my place bos Sunday but instead took my active pill! I ate Popeyes today and I feel  little sick but I'm not sure if it's from the food or from me getting my period because I get it three days into my place bos and tomorrow is my third day, so the real question is here is that can I still possibly get my period while on my active pill
