birth control, I need an opinion?

Jillian
Hey girls I was wondering if I could get an opinion/information. I've been taking the combination birth control mono-Linyah for 4 months and it's been working great, I've never missed a pill or taken it late. This past Wednesday was my last pill of hormones before the placebo pills, I had sex and he didn't pull out I know sperm can live up to 5 days in you I'm wondering if there's a chance I could get pregnant now that I'm on the placebo pills. My period hasn't come yet but that's been normal for me it doesn't come until the 3rd day of the placebo pills and I'm only on the 1st but I'm still a little concerned.
