new to birth control

Hello! I just started birth control on Sunday 1/29/17. I decided to start taking the pill at 8:00pm. I was doing pretty good until two nights ago, I took it at 8:35pm. Do I have to continue taking it at 8:35pm or 8:00pm? And also, can I start having unprotected sex without any worries? Or should I wait? Or should I still use condoms?
