can someone clear this up for me? protected or not during placebo week?

Okay. I've read that you are protected during your placebo week as long as you've been faking your active pills correctly and consistently. BUT then I've read that you can become unprotected once you've missed a dose or two of pills. 
Isn't a placebo week missing a whole WEEK of pills, not just a day or two? 
Are you only protected during the placebo week because you've been taking it for 3 weeks straight? And if you miss a pill or 2 you're unprotected because it's in the middle of the active pills? 
Why does this confuse me lol 🙈 I've been on birth control since March but just recently we stopped using a condom, and last night had sex but I'm on the placebo week. So it got me thinking and now I'm all ?¿?
