No period 2 weeks after stopping birth control. Had protected sex a few times and took birth control on time almost every time. Pregnant?

Pregnancy test... The only way to know if you are pregnant is to take a pregnancy test. Chances of pregnancy are decreased with protected sex and appropriate use of birth control pills; however, neither is 100%. Take a pregnancy test. The hormonal changes involved with stopping the pill can affect your period; however, if your cycle doesn't normalize be sure to follow up with your gynecologist.
