PREGNANT????

Hi! I began taking Junel 1/20 in July. I take those pills RELIGIOUSLY. I've never been late or missed one. I haven't had sex in about a month and the last time I did, I started my period the next day after. Yet- today, a week before I'm supposed to begin my period and 4 days before my placebo week begins, I'm experiencing cramping and light pink discharge??? Why??? Google says I'm pregnant but honestly I'm calling bs. We always use condoms and even still he always pulls out, and I always take my pills. I thought that was the trifecta of preventing unwanted pregnancy only second to abstinence. Please help me. I'm totally freaking out.
