Can Next Set Of Oral Contraceptives Be Continued Inspite Of Not Getting Periods?

I take an oral contraceptive pill called Diannette. I am on my 1 week break and expected my period on Thursday or Friday. However, it did not come and I am due to start my next set of pills again tomorrow. I did a pregnancy test which gave a negative result. Should I stop taking the next set of pills until I get my period? I have always been regular in the past.
