Mini pill and no period

Grace

I started taking the mini pill on December 29, and am on Ed a week late for my period. Is it normal to skip your period right after starting the pill? I had brown/dark red discharge for about 3 weeks prior, and now it has stopped. I take all my pills on time and my boyfriend does finish inside of me, but again I take my pills at the same time everyday. Is it normal to skip like this?
