Once I take the morning after can I continue with the pill as normal? Or won't it induce my period?

But won't taking the morning after pill mess up my whole routine of taking the pill?
Yes we are up to date, and seem to be both fine, this is one of the very few times we have actually engaged in unprotected sex as we usually use a condom.

I started using the yaz pill 11 days ago(today will be day 12) but I have noticed that I have been spotting for 5 days now? Is this normal? Apart from that I had unprotected sex and my partner came inside me, should I take the morning after pill to be safe? Am I safe?
