What to do

Ive been on the pill for a couple of months now.. I usually skip the sugar pills because i dont like having my period lol. Last time i actually took the sugar pills was back in April.. Jun 18th bf and i had sex and he came inside and this monday i started taking the sugar pills, its already saturday and still no period? I have had cramps this week like if i would get my period but thats about it? What should i do? Sunday will be my last day on the sugar pills, therefore on monday should i continue taking the new pack or wait?
