It is possible! With DS I became pregnant within weeks of stopping the pill, I'm pretty sure my "normal period" hadn't even arrived yet. With this one, I stopped the pill about 8 months before I fell pregnant. But my period didn't return until about 3 months after I stopped. We weren't trying to TTC (using condoms) until my periods were "regular" (My cycles are loooong), I wanted to get to know my cycles before we started as we were trying for a girl.
