I got my period on 08/29/2010. I took the plan be twice after that the first on was on 09/08/2010 the second one was on 09/13/2010. I haven't had any period since then, is there a chance I could be pregnant or that's normal not to have a period for almost 2 months.

Did you take the plan b after you had had unprotected sex? What time frame was it from the sex until you took the plan b?

Did you have bleeding after using the plan b? Most likely your cycles are off due to the two doses, especially so close together.

It certainly would be wise to try a pregnancy test however... be sure to follow the directions exactly. If negative, either wait until next month and see what happens or see your doctor for a blood test.
