Pregnant?

I’ve been on the BC pill for a year and have always taken it perfectly. My bf and I have had some raw sex but he never cums in me. <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> says my period is a day late (almost 2 now) but my period last month came 3-4 days earlier then usual so i think it’s going by that? I just took my second period pill and usually my period comes by the 3-4 pill. I’ve been feeling light cramps but it’s still not here. Should I be worried?
