Period late? Or is it my birth control?

Kenzie

So I was out of town when my sugar pills ended and I forgot to bring my next pack so couldn’t start it until I got home (3 days later).

Since I started my pack late, will my period also be 3ish days late? I took all of my pills on time and my boyfriend and I always use condoms as well, but I’m a little bit of a worrier when it comes to that kind of stuff.
