Is it risky to skip just one pill on my birth control?

I know the pill is only as effectve as the correctness of taking it. But my 28 day cycle pack became 27 (I lost one) I just didn't take my very last one and started my placebo week one day earlier than usual. (which made me start my period early too) I was planning on beginning my new pack a day early as well. **Side note: I have not been sexually active for this cycle but since my bf has been gone for training, he's coming back in a couple of days (still on my period) and I just want to know if it'll be safe once I resume the next pack or how long I should wait during my period and after. Let me know if that was confusing or if you understood it. Thanks. 🙂
