Hi! I Am Taking Ortho-try-cyclen. I Accidentally Took The Pill

Hi! I am taking ortho-try-cyclen. I accidentally took the pill pack backwards (started on week two and then week three). Today if I take a pill, I will be taking my first white pill with a lower hormonal dose. Since I had unprotected sex yesterday morning, I am worried about taking a pill with a lower dosage. Should I double up on two white pills or am I still protected?
