period came after missing pill

So on Friday Saturday and Sunday I lost my pack so I couldn't take the pill but found it on Sunday. I took Fridays and Saturdays on the Sunday, then Sundays and Yesterday's yesterday. Anyway so I saw spotting but just put that down to missing 3 days, however I woke up this morning and I am now heavily on my period (It's normally heavy anyway). Do I carry on taking my pills or have a period break even though I'm halfway through my pack?
