I normally take the pills like normal but & my doctor said that I could skip my period when I don’t want it. The last time I done that, I skipped the “placebo” pills and started a new pack & I had my period until the next pack. I took all the pills in my last pack except the placebo ones this time & started on my new pack. I started to feel cramping the 2nd day & I’m so confused. Does this mean the birth control isn’t working like it should or what?
