I'm having the exact opposite question as everyone else.. Usually people ask what day they will start their periods on placebo week (the answer with my old BC was the 3rd day). But now I'm on my 2nd full month of Zovia and I start my period and painful cramps the first day! I take my pill at 7 but since today is the first placebo day I started spotting brown at 1pm. Is staring my period on the first placebo pill a common Zovia Syptom?
