Did BC (Pill) effect your period

I’m new to bc and I’m curious if it will mess up my cycle should I expect my period to come later ? Or should I just go with my <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a>. prediction (my period normally comes when <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> says it will. )
