Can I do it now?

So Saturday 9/26 was the 7th day I had taken my birth control. On my pack it says after 7 days of taking it correctly (which I have been) then I don't need another form of protection to have sex. Does it take longer than 7 days for the pill to start working for me? It's just I was planning on having sex this week and of course use a condom, it's just the last time I had sex the condom broke twice and I wasn't on the pill then so I had to use plan b. I just want to know if I'll be okay if the condom does break again?
