I take birth control daily, but do not take it as diligently as a should. I take pills at all different times of the evening and sometimes even take it the next morning if I forgot. I had unplanned, unprotected sex the last day of my pills. I took Plan B One Step 9 hours after sex. My period was supposed to start yesterday, but it still had not. Should I be worried that my period is late? Is this typical of Plan B?

Your not taking pills properly make them almost useless, so you need to start taking them properly to really have effect.

Plan B is not 100 percent effective.

So could you be pregnant, yes of course you can be.

But plan B does often make you miss or make it late on the next perod.
