When am I protected?

So me and my boyfriend both live in other countries. I am gonna visit him this Christmas. We are pretty careful with sex as, we don't want kids yet, as I am 10 years younger than him (we are legal) point is, when am I protected enough, I use the mini pill meaning 3 weeks taking it and one week not taking it, so to continue...

So if I would take my pill the beginning of December, will I be protected around Christmas?
