I took the Plan B pill on February 21,2011, had unprotected sex on February 20, 2011. My last period ended either February 17th or 18th. Now we are on March 29,2011 and my period is more then 14 days late. What should I do? I also feel free sick.

I think you should take a pregnancy test and see what the results are and then also make an appointment with your doctor for a check up and take it from there. Do you feel that you have any occurring pregnancy symptoms like tenderness to the breasts and nausea?

You have pregnant... go and check !

Plan B can mess up your period, it can also make you feel "ill". If you're concerned that the plan b didn't work then try a pregnancy test, or see your doctor for a blood test.

There's no way for us to determine whether you are pregnant. You'll have to test to make sure. That's the only way to be 100% positive.

Good luck.
