Is it bad that I started taking birth control while I wasn't on my period?

Abby

I started taking birth control pills about a week before I was supposed to get my period. When I went to Planned Parenthood the nurse didn't say anything about starting it on your period so I didn't think about it, and then I read the instructions and it said to start on your period.

Is that bad?

Will my period start before I'm taking the sugar pills?

Should I go off and start again next cycle?
