Coming off the Pill

I've been on a contraceptive pill for a couple months now, however me and my boyfriend have now split up so I no longer need to be protected 😕 I stopped taking them on the 17th (today being the 19th) and I've just got my period again today! Will my period go back to my normal cycle date or stay round this time of the month as it was pretty good at staying around one time of the month?? Thanks in advance!
